Rookinheimer 

A person that is both a rookie and a heimer. Not to be confused with the 'dingleheimer', this individual is (a) wack, (b) a noncontributing ZERO, (c) someone you definitely do not want to party with, be associated with, and especially not seen with. However, a person can experience rookinheimer lapses in their daily routine, not to worry, these will pass.

Johnny "Two-Timer": "...saw Sean at the party last night slamming Twisted-Teas with his girlfriend...what a rookinheimer!"

Roominheimers 

The act of going from one room to the next, with the intent or purpose of accomplishing something, then standing there, completely perplexed - wondering why you went into that room?

Why am I in my kids room - ugh, roominheimers is acting up again!
