Doctors diagnose many teens with "fat man syndrome" because they are injured due to their BMI index that is off the charts. Generally, heel injuries are the most common causing the person to limp like a chodus maximus. Be aware that a person limping might not have "fat man syndrome," but instead chode spasms.
That kid limping looks like an idiot because of his heel; we probably have another case of "fat man syndrome."

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.

While you're doing your bitch or significant other in the anus, slyly replace your penis with larger and larger cylindrical objects until you can easily slide in a can of soda. At this point, you no longer need to hold your soda.
I got tired while boning you and had to set my drink down, but we don't have one of those mattreses that doesn't transfer energy, you know like in those commercials with the wine glass and the lady, yeah so I had to stuff it in your ass like a fat man's cupholder or something. Gosh that's a catchy name... anyway, so how about you and me hop down to the Canadian mattress and proctology imporium for all of our medical and bed needs.

2. Did you use a shower cap?
1. Yeah, she said we couldn't do anything until I put it on.
