The L Bomb is the action (usually in teen relationships) of saying 'I love you' to someone you've been
dating or know well and like a lot, dropping the l bomb is a
massive deal, mostly for guys as a lot of teenage girls are assholes and when this occurs are prone to saying things like: 'aww, thanks' or 'you're so sweet' and sometimes
even 'you know, I think we should just be friends'
Guy: I love you.
Girl: Aww, that's soo sweet.
Guy's Friend: So did you drop the l bomb?
Guy: Yeah, but she totally friendzoned me.
