A thrasher is a "cool kid" which pretends to be high and always says "SUP BRO" every 10 seconds. They typically don't have a fully developed brain and carry a skateboard almost everywhere. They have thrasher merch and cheat on homework assignments. Girls are into their not yet developed brain.
"Is that a thrasher?"
'Yeah, hes so dumb"
Girls: "OhhhHHHHhhhhhh"

Someone who listens to thrash metal. Characterized by their inability to hold a job, stay in school, keep a relationship, or stay sober, and their tendency toward violence. Thrashers are commonly found in record stores, music venues, parties they're not invited to, the back of police cars, and passed out in strange places.
WARNING: Do not insult extreme music around a thrasher or risk severe injuries.

An uber-cool and ravishingly good looking internet forum dweller who flits between threads like a skylark betwixt the clouds, posting seemingly off-topic missives about monkeys, dolphins and highwaymen with like-minded souls, much to the annoyance of other forum dweebs.

This is called "thrashing". Those who do it are "thrashers".

FACT!
