A person who has
smoked enough
sherm to acquire serious brain damage. This does not take
long to happen, and is often characterized by trembling, drooling from a slackly held-open mouth along with a rambling, mostly incoherent pattern of speach.
Oh man, that Reggie, he ain't
nothing but a shermhead now; he ain't no damn good for
nothing! Alls he is is a
twitching drooling fool slinking around in the alleys. He melted his brains real good.
Dumb motherfu**er!
