Get the fat sound mug.
The sounds one typically associates with a fat man. The 'daaaaaah' of sitting in or the 'hrrrrrnnngh' that accompanies the getting up from a chair for example.

All fat man exertions come complete with a fat man sound.
You're so chunky now you make the fat man sounds and don't even realise it!!

An insult toward bitter females, who may or may not be fat and/or ugly, that think they are above people who are more attractive and can attract the opposite sex easily. They also generalize about people to make themselves feel better.
Bitter Female: "In my books all pretty boys and weight lifters are jerks. They think they are so great, if one tried to walk up to me I would ignore them."

Random Person: "You sound fat, those types of guys would not want to talk to you in the first place."
