Lmb&bo 

Derived from lmbo. Aka Lmbnbo. Means "Laughing my boobs and butt off" if you're a girl or "Laughing my balls and butt off" if you're a guy; or whatever you want it to be as the "b's". It is said when someone and/or something is extremely hilarious. Also known as lmfao: or to say " Look at him/her! HE/SHE is LMBNBO or LHBO/ LHBO!!". It is just as funny, and/or funnier than lmfao. Pronounced: "Limb and bo", "Limb 'n' bo", or "Limbnbo": when you can't pronounce "Lmb and bo" in hilarious conversation. Lmb&bo also holds a second benefit: to say lmfao without cursing.
