Oh sorry, you're right - its "far too" small! "I've a big butt and i don't care about physics and the perspective!"
There's a very visible line in these types of jokes where it crosses from "funny" to "for the love of god shut up already" Having large boobs makes sense and is sometimes cute. Having fat butt cheeks is ugly and specifies your status as "morbidly obese". Seriously, there's this thing called common decency.
,and if 1 SS Soldier Facepalming wasn't enough. You get three SS Soldiers to facepalm, and if you can get a Nazi to Facepalm, you know you failed......
Well now you're trying to take personal kinks and pass them on as fact, let the people have there fun.
