almost exclusive to audiophiles, the skull crease is identified as an indent in ones hair, caused by a person's headphones pressing down his/her hair, making a 'crease'. this often happens when you play lots of music, or you just put your headphones on to block out what your teacher is telling you. this can also occur when a woman uses a headband or elastic to keep their hair from flying everywhere

An urban professional who continually re-wears suit pants to work every day, but fails to iron them, thereby creating a proliferation of creases behind the knees and alerting everyone nearby to the fact that this person is a crease monkey.
A crease monkey will also tend to have poor hygiene and wear outdated clothing. They tend to be social introverts as they have no real friends to point out to them that they smell, their clothes are outdated and they have tons of creases behind their knees.

"Wow, look at that ugly green suit, what is that from 1981?"
"Haha, probably. I don't think he's had it pressed since 1981 either, what a crease monkey."
"Total crease monkey. I bet he smells."

The nerd crease happens when a red line on your stomach appears from slouching over a computer desk. This can happen from hours of playing such games as: Minecraft, World Of Warcraft, Runescape, league of legends and various other games.
Oliver: Hey check out my stomach its got a redline on it!
Andy: Woah that looks like a bad case of nerd crease you should stop slouching over your desk Oliver!
