Collector's anxiety 

A sentence commonly used by a twitch streamer called Pointcrow, in which he refers to the anxiety of wanting to collect everything possible. It was first used in his first YouTube video and in one of his early twitch streams, it is now used to playfully ridicule him in stream chat or comments.

“Hey guys, PointCrow here. Do you ever get collector's anxiety?”

Yeah, I know that Taylor's a sperm collector, but I don't have to worry about getting her pregnant. I've already been snipped!

poop collector 

Also, the poopman.
Comes in his poop truck to suck the poop out of the sewer system (and other things that get stuck there).

The poopman is very popular in places where they have cesspools in the houses (like in the majority of Europe)

Oh my gosh! The poop collector is digging with his poop scoop in the poop truck's storage space, looking for gold!

Nah, he's just stirring the poop!
He loves the poop so much that he can't wait to make love to it when he's home!

nostril hair collector 

This is a comical way of saying that someone has weird, solitary habits or obsessions.

friend collector  

A person who, as the name suggests, collects friends on Facebook, Myspace, or other social networking sites. The collector typically does not know the people they are adding, and may do this for one of two reasons:
1) To create a false sense of e-popularity
2) To lurk people and otherwise gain access to information they have no business reading.
