What is the difference between being a camper and a sniper?

"
When a sniper kills you, you tend to go "Jees that guy is a good shot". When a camper kills you, you tend to go "$@~*&^%££$!" "

it depends what weapon they have.  Sniper rifle makes them a sniper, someone with a knife in a corner that chases someone when the walk by is a camper.

A camper will ususally only kill me once before I get him. I use sniper all the time but I use it pretty aggresively like a assault rifle but with one shot one kill abilities.

I remember when the only campers in COD were snipers, not people camp with LMGs and Thumpers...

What do you call a sniper with an ACOG'ed sniper rifle used as an assault rifle?

Snipers change position after every kill. Campers don't.

In games, a sniper is someone who camps in a strategic area with his weapon of namesake, usually in such a place that provides both cover for him, but also a good surveillance of the battlefield. A camper is someone who sits hidden in a corner that often needs exploits or devoted attempts to get into and shoots anyone who haphazardly happens to stumble into their vicinity.

a camper goes online and makes a post trying to justify why they are a camper.

I see snipers and campers as two different types of player.  
 
Sniper: Someone who sits at range with a scoped rifle intended for long range work. Generally not suitable at close range. 
  Camper: Someone who hides with an assault rifle or SMG. Owns at close and medium range.

Camping is like porn, you know it when you see it.
If we are referring to MW2, its practically every new addition they put into the game. 

In a game a good sniper knows to stay mobile. If you "camp" as a sniper in the same spot people will know where you are. If you stay mobile and just pop a few kills per location, you're sniping, not really camping at all.

" @Aaox said:

" Snipers are military-trained units with sniper rifles. Campers are families who can't afford a real holiday trying to make do with what they have in their country, using commodities like tents, spam, and fishing rods. "

I'd say:
 
A sniper peaks out of his nest - meaning he is inside  a room looking out of the window.
 
A camper is looking inside his nest - meaning sitting inside a room guarding the door.

Sniper is a camper... but, i can't explain of this
