"Laughing My Ovaries Out"
A phrase coined by V and defined by Martha. Long story short, V has a way of speaking where she likes to stretch words and make them sound funny. LMAO becomes lmoo, no becomes nerh, yes becomes yesh, and so on and so forth.
Obviously, it only makes sense when said by a female, but it's oh so amusing when said by a male.
B: Let's go knife some hoes.
