4. And I ate two of 'em. Mmmm.

Was a truly terrible experience.

Nothing out of the ordinary, like 2 or 3. 

"1  I hate burgers, and fast-food in general.  I have a feeling I am not welcome here. "

3 myself! Could handle much more, but have yet to try!

Ate 3, but they were pretty small, had a double bigass bbq burger once though.

Had four from a BK stacker or w/e, but I've had the tripple whopper a couple times which is actually a lot more meat.

5 but it took me a good 2 hours.  I originally ordered a triple at Wendy's, but they accidentally put 5 on there.  I was sick for a good 3 days after that since it was the greasiest thing I've ever eaten.

5 but they were super thin. About the size of a double quarter pounder in thickness but much more filling and heavy due to all the meat.  
  
 

I got a "Quint" burger at Blimpy Burgers in Ann Arbor. It's been featured on Diners Drive-Ins and Dives too. (food network show)

6. My bro works at McDonalds and they had meat and stuff that needed to be used, nearing used by date or something - and I'm well reknown for my gluttony! So he brought me home this bigass burger.
I kind of regretted it afterwards, though in all fairness I was actually feeling sick before I ate the burger. Would I do it again?... Probably.

4. BK Quad Stacker.

Eight

triple stack from burgerKing. I'd definitely go for a 4-skie

Probably 3, but I at least eat 2 patties per burger. Sometimes I have 2 burgers with 2 patties on them.
 
This forum makes me hungry...

today I might get a 4 quad

3. 
 
i had nightmares after that.

I've tried three.

Two. Never more.

2 with a spicy chicken sandwich in the middle. Called a McGangBang. One of the McDonalds in my town makes them and they are delicious. Very bad for your health but then again nothing from McDonalds is.

had a quad stack from burgerking on saturday. I told you I would!!

" Octo-Mac, boys. 8 patties of glory "

It was either a 3 or a 4 from the Burger King in whatever airport it would be in America that's in a state that starts with P if you flew from Rio to San Francisco and did a changeover.  Airport also has a restaurant called 'Chillies' or something, and an awful ESPN bar that charges about 10 dollars for a pint of Sam Smith's "Not quite right, but better than most yankee filth-water" beer. 
 
8)

Four.
 
The largest I've ever had was this triple-1/2-pound-patty monstrosity I cooked up once.
 
I've also done a McGangbang (a whole McChicken in between a McDouble/Double Cheeseburger).

I think 3. Was on a McDonalds in Ireland.

Only two.

2

oh and because someone will point out I'm not the main character in American Psycho, about 2 I think, that's the most for me, never hungry enough for more. 

I got my boss a 15-patty for his birthday, and he downed that with fries and a shake.

I've had 3 once, but they were pretty thin. Like, added together they probably would've made 1.5 patties.

I AM NO AMERICAN!!! "

Three. Out of sheer curiosity (okay I was also pretty hungry at the time) I said, "hey why not try the triple bacon deluxe at Wendy's." Turns out it's not the volume/mass of food that's the issue (as even a typical triple burger still comes out to be less than a pound of food), it's the density. It's far more difficult to eat one triple burger than it is to eat three separate burgers. To that point, I find that even eating a double burger is a fairly unpleasant experience.

I made one with five once. It was fantasmical. I also shortened my life by about 7 years. 

Just two...

once you break the 3 mark theres no going back, you just want to keep pushing the limits

6!

1; burgers are terrible in general, though I do like chicken burgers on occasion.

4. My colon was angry.

4 for me, was a BK Quad Stacker. Not the hugest of sandwiches, but the 4 patties made up for the size.

There's a place round here that do something called a Giant Burger, 4 patties. Me and my friends have made it through the patty to tell the tale... it was... awful.

My buddy bought a friend a 52 patty cheeseburger (with the cheese on) from McDonalds as a dare. It came to ~$65 CAD. The video is on FB if you want, I can rip it and show it here.
