Moon Heads are thugs (or chavs in britian) who can barely string together simple sentences without the use of the F word.

An easy way to detect a moon head is the repeated use of the phrase "arghh mate it woz such a batty crease", a Slight over bite, usually a dimond earing and the trait that got them their name; their huge, oily, spotty, shaven skulls.

In some cases they will have thick circular glasses and/or will be very short

----CAUTION----
These will be the cockiest little sh*ts you will ever meet, try and avoid this breed of Moon Heads.
Moon Head: "F*cking hell, you F*cking emo!? "

Man: "Erm no i'm just wearing skinny jeans lol."

*Moon Head turns to it's Moon Head(s)*

Moon Head: "ahhhaha f*cking mate!? f*cking batty crease mate, f*cking emo wearing f*cking skinny jeans - F*cking state mate, i f*cking tell you Haha"
