Often known for "Tweeking" things...usually on speed, the male "tweeker"
will often obsessivley take things apart with disaterous results like VCR's..
Radios, or other gadgets into the wee hours of the morning.

When bikes are involved the formula often goes:
Tweekers + Bikes = total chaos, distruction, etc.

I've unfortunatly delt with more than my share of them lately.
It's a big problem here.
