A BOLO
A bolo is a Nigerian idiot who thinks they're funny but nobody laughs. They just roll their eyes and mutter curses.
'Bro, you just called the principal a bolo? You're gonna get suspended for sure.'
'That guy in class tries to be cool every day. He's a bolo.'
'My uncle is a bolo. He told a joke and no one laughed. He cried.'
