Skin Yamaka (Yarmulke) 

When a middle aged man is balding only in the spot where a Jewish Yamaka (Yarmulke) would be worn.

Student 1: Dude, our teacher is getting old. I think he's balding!
Student 2: Yeah! I think he has a Skin Yamaka (Yarmulke)!

Yarakashi 

This term has been taken from the Japanese language. It describes agressive fans who have bad manners on the internet, concerts and threaten lives concerning Johnny's (A Japan entertainment agency which focuses on males).
They even plan an attack on a group of JEs, because they like the other group more. They'll go as far as bringing knives to demonstrate their support.

Rumor: Nino's thumb was once broken because of a yarakashi.
Rumor: Yarakashi's love to insult aiba during concerts because they think he is 'stupid'.

Hip-hop Yamaka 

A ski cap rolled up so it just stays on your head. It looks like you're wearing a large barely unrolled condom with-out a tip.

Many of the henchmen in the old Batman series wore Hip-hop Yamakas
