When someone, usually a biological female, is throwing some beef down on the fat cake. This is more prominent is Spring, specifically after the 1st heat wave.
Babe, have you been beefing the fat cake? Yeah, I can tell you have, smells like it.
Cunt cake: when the weather is hot out and a womens yeast infection is baking. Looking like a cake by the end of the day.
I took home that slut from the bar last night and she had a cunt cake the size of a footballl.
Taking a load to the face by a carrot top aka red head
I spent last night carrot caking Mrs. Jones
When a dude nuts inside of a big butt.
Friend 1: Do you see that girl? She's got some cake!
Friend 2: Yeah man, I want to give her a King Cake!
