If you need to look this up, it's probably because:

A. You don't speak English.

or B. You're two dumb to live.

If A, to put it simply, Oxygen is a substance found in air, which you need to stay alive and your body collects by breathing. If B, kill yourself.
I didn't know what oxygen was, so I died. :(

Someone so useless that each breath he or she takes is just one less lungful of oxygen for someone or something worthwhile.

Get the waste of oxygen mug.
Person who is inept at everything he or she does. To be in the same room with these people is to be stupider in every sense of the word. These "oxygen eaters" are born, eat, poop, and die, while serving no purpose at all except to eat my oxygen.

Completely useless...
