Wet-Brain

1.) A person who does a drug (speed/ice) just to put out the impression of something he not, and only acts tough when surrounded by so-called homies who don't like him but it's where everyone meets up to use drugs ended up doing a tad bit much more than what he can handle so now he's all frentic and sketch of those who are really there for him trying to be there for him.

2.)The effect on ones after smoking pot chronic and lasts about two weeks. Being wetbrained causes random intervals of spacing, forgetfullness, stupidity, and occaisonally blackouts.

Ex; Ay remember when our bud connect would hook us up before he was all wigged ouy, "We all used to get high at his crib and smoking up pre-rolls from & watch South Park and now he's all Wet-brain from all the snorting thinking everybody is after him!"
& Yet he's still the only person who supplies you with the best weed around town so you can't avoid him.
