Traditonally "Sir Twampskie"... refers to a dealer who won't sell you larger than a twamp sack. So if you want anything close to an eighth you have to buy three twamps, for $60.
He/She always has bud to sell no matter what quality and they will gladly drive to your house to sell it to you.
Person 1:Whats up twampskie are you ganna sell me an eighth this time??
Person 2.(Twampskie): Sorry all I have are twamps, I can give you three for 60.
Its good shit though.
