Toilet Sitter 

The backside of any person, individual. The butt cheecks, the rear end, the caboose, the ass.

Person One: Look at the large toilet sitter on that bitch.

If the 'toilet sitter' of the person is some hot babe, then, "Awww, yeah, she could sit on me any day of the week."

If the 'toilet sitter' is from a larger heavyset woman, then, "(SPIT TAKE) HOLY SHIT, WHAT? (VOMIT.)

(Not just for females, but males as well.)

Pickle Sitter 

Pretty self explanatory... one who sits on pickles. Usually practiced by homosexuals who enjoy the sensation of pickles penetrating their asshole.

Hey Joe, don't be alone in a room with Randy... he's a known pickle sitter.

Couch Sitter 

Someone who frequently opts not to go fishing with his friends. Someone who would much rather talk about fishing than partake in the actual activitiy.

Also someone who waits for all the leg work to be done (I.E. spots found and techniques figured out) then reaps the benifit of all his friends hard work.

Person #1 - Hey man you want to go fishing tomorrow

Khalid Barkawi - Na, I've got some real important things to do.

Person #2 - O really like what?

Khalid Barkawi -Well actually nothing I was just waiting for you guys to figure it out so I can guaranteed catch fish. Why should I help when I don't have to?

Person #1 and #2 - GOOD POINT! Your a couch sitter!

Floor-sitter 

Someone who, for some reason, prefers to sit on the floor as opposed to furniture.

Because Hannah was a floor-sitter, she chose to sit on the floor instead of the couch, even though there was plenty of room.
