So, Thrasher's a skate mag... but for some people it's an aesthetic. If you wear thrasher and shop at zumiez sorry dude you're a poser.

A person who believes in God but dispises him, listen to the awesome music genre Thrash-Metal and pray’s to the holy Cliff Burton up in the sky.

Famous thrashers: James Hetfield, Tom Aray, Dave Mustain

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.

Anyone, male of female, who is predisposed to arbitrary violence.

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!

Crazy white kids (between the ages of 14 and 16) who drink alcohol, vape in the school bathroom, and wear Thrasher.

people who listen only thrash/death/black metal and say that others sucks. very often they're just posers who try to look cool and really don't like such heavy music.
