D-Man: “What are you doing?”
New Guy:"Yo Mama."
D-Man: “Excuse me?”
New Guy: “Yeah, but she fat.”
D-Man: “What?!”
New Guy: “She’s so fat, her biggest fear isn't muggers -- it's poachers.”
D-Man: “That’s not very nice. She’s just big boned.”
New Guy: “Big boned ... like a dinosaur?”
D-Man: “I am going to kill you.”
New Guy: “It’s just a joke, dude.”
D-Man: “Oh. OK. Well … your … your mother is so … she’s so obese, that she has to go to Weight Watchers on a Tuesday night and then she has to stand on the scales in front of everyone, and if she loses weight, well, that's cool, but if she doesn't, she gets depressed and then stops at KFC on the way home and then she gets home and eats a whole lot of chocolate biscuits and a packet of salt 'n vinegar crisps and then moans about how she wishes she could stop eating.”
New Guy: “Yo mama's so fat, all the restaurants in town have signs that say: Maximum Occupancy: 240 patrons, Or yo mama”.
D-Man: “Well … your mother … your mother is so… fat that she has to wear clothes that have been specially tailored for women of the larger persuasion.”
New Guy: “You suck at this.”

Oh Yeah? Who's mama fat now?!
In your face.
Bearch.
