Usually used in sentence sarcastically, a Compression helmet counteracts and protects against the effects caused by the "fun theory". The "fun theory" states that if an individual has too much fun within a short amount of time, consequently, said individuals head will blow up.

Get the Compressed girl mug.
Athletic underwear that look like shiny boxer-briefs and are supposed to function the same as a jockstrap (support/protect the testes) but don't. Fit awkwardly and strenuous activity causes your junk to move around which leads to lots of awkward adjusting. Have become very popular with young men around the country who wouldn't be caught dead wearing a jockstrap in the locker room, even if it men't wearing something as uncomfortable and ineffective as Compression Shorts.
Teammate: Yo, no one wears jocks anymore bro. You need to hit up some compression shorts. Shit be stylin. Yolo.
