Old Head 

1. Someone who has been in the scene before you or your group.

2. Someone who is still in the scene beyond the 'acceptable' or expected age.

Often form cliques of their own and try and school youngin's on how things used to be back in their day. A scene-specific 'senior citizen,' for all intents and purposes, in activities that would kill normal seniors citizens (drug/club/rave scene).

Yeah I know that guy, he's an old head.

Fly Head 

A 'fly head' is used to describe someone's testicles that are bigger than their penis. The testicles represent the fly's large eyes, and the penis represents the thin/small mouth of the fly, thus being called a 'fly head'.

tired head

A state of mental exhaustion, typically found in mind-numbing Corporate America, from too much/too frequent ideating, critical thinking, problem solving, innovating, strategizing, or any other fancy word used to describe the overused concept of thinking outside of the box. Effects can be exponentially compounded when experienced within a rigid, process-oriented and/or risk averse environment.

Our attempt over the past two months to re-invent our company's poor excuse for a long-term strategy has officially given me tired head.

Map of Your Head 

A song by the English alternative rock band, Muse. The song can be found on the Hullabaloo Soundtrack and on the New Born single (CD2). Though, the song is relatively simple it may put you in a state of absolute bliss or calmness. The singer, Matthew Bellamy, uses his voice and the gentle lyrics in a way that allows the music to seep into your veins. You may or may not find yourself in a state of utter euphoria.

person 1: Hey, have you heard Map of Your Head, by Muse?

person 2: Oh yeah, makes me feel like I am floating in thin air, wearing only socks.

person 1: Yeah, it's a pwoper song mate.
