To boom someone is to slam them down to the ground by grabbing their mid section, picking them up and slamming them down to the ground on their back.
Nico didn't like the nasty texts he was getting from somebody. So when Nico saw him, he didn't even give him a chance to punch him. Nico just ran over to him and boomed that cat and knocked him senseless.
a word used to describe someone usually a woman who has an incredibly large arse, however can also be used to express a back fat issue,although male boom does occur the female variety is much more entertaining can also become mega boom
