Toiletbrush Tripweed 

A board user from GameFAQs. Took his username from the character Guybrush Threepwood. In Money Island 4: Escape from Monkey Island he got called "Toiletbrush" by a stem picture of a ship.
Then the last name underwent a similar transformation, pointing at the city where he was born, Amsterdam, where people "Trip on Weed"
And this is how his extremely kickass username got in existance.

"That Toiletbrush Tripweed dude is weird"
