Means to have been a long time ago.
Commonly said by
Green Day in the song "
Whatsername" in which the lyrics "forever ago" are repeated several times.
It can also be said by stupid retards without good grammar, people too lazy to express themselves in other words, and by people who really DO
feel it's been forever ago.
Person 1: Hey, has that girl you met at the
DDR party
called back you yet?
Person 2:
Nah.... it's been forever ago; dude, she isn't calling.
