a word to define a tweeker but its more fun to call people twakers.

Literally everyone, ever. Including the writer of this definition.

A Twaker is the cross between a Tweeter (person on Twitter) and a Lakers fan.
So a Twaker is a Lakers fan on Twitter that follows everything and everyone Lakers! 24-7 LakersNation and live Tweeting during the games.

a Twaker is the cross between a tweaker (person on crack) and a cracker (pretty much just a cracker i can't explain)
so a twaker is what you call people when they are acting really stupid or just need to be called a name and that is when you use this wonderful word
