look up any word, like kappa:
 
1.
An acronym meaning "Falls Over and Jacks Off"

Derived from the recently invented foatu, but the connotation of this word is much different. Foajo is used when something extremely happy or pleasurable just happened.

Foajo is pronounced like you're saying "foul" without the l, and the jo is said like your friend's brother's name, "joe".
Mike: OMGZ d00d, look at her.
Bryan: @_@ FOAJO!
