all your base

Some stupid internet phenomenon that has geeks across the country drooling with amazement at some bad grammar. The common geek inserts the phrase "all your base" into any random posting on a website, and therefore thinks he is cool. It originated from some bad Japanese translation in a Videogame called "Zero Wing". People thought this was amazing, and started saying all your base all the time. See pwned and numa numa.

Translation:
(OMG ALL YOUR BASE HAHAHAHA)

5th Base

When a guy is having anal sex with a girl and he takes a large hoop earring, interests said earring in her butthole to make it gaping and then the male drops his balls into her butthole and removes the hoop earring for a tight fit of his balls in her butthole

Dude 1: Yo bro i just hit 5th base with this bitch
