A fork of Rural Dictionary
When someone you don't like says something that's mad real.
Nick can't keep it 100 because I don't like him, but he can keep it 99 because he says trill shit.
COSR MONZR WE KEEP IT 99 BECAUSE SOMETIMES WE BE LYING
Keep it 99-having to lie at times cuz we give no fucks Oh nah that's my cousin Nah he aint gonna fight don't worry
Coming from the saying “keep it 100”, meaning to keep it real. Keeping it 99 means the opposite of this
