motion concentration sickness 

Different from regular motion sickness, sufferers of motion concentration sickness can enjoy being in a plane, train, or automobile as long as they are not concentrating on something other than the scenery.

Sarah: (driving) I think we missed our turn back there. What does the map say?
Kat: (looks at the map) Yeah, we're about two miles past it. Pull over, I think I'm gonna to puke. Reading the map gave me motion concentration sickness.

Thomas tried to study for his exam while on the bus, but his motion concentration sickness kicked in and gave him a headache that lasted the rest of the day.

Stoner Concentration 

A card game used to test the potency of your marijuana. The more difficult it seems, the stronger the weed.

Stoner1: "Stoner Concentration is played like regular Concentration, only the cards are dealt face up. You have to turn two cards over and find a match."

StraightPerson: "But that's crazy!!! You're only matching the backs, and all the backs are the sa...."

Stoner2: "Cool, man. Blaze one up and deal!!!"

concentration tongue 

Much like drummer tongue, the act of unconsciously sticking the tongue part way out of the mouth while performing any task requiring concentration.

puerto rican concentration camp

When a Puerto Rican man ejaculates such an exorbitant amount of semen into an object, leading to the murder of millions of would-be Puerto Rican children in one place.

This dude Hernan has dumped so many loads in his mattress it's like a Puerto Rican concentration camp.
