Trashboat
An individual who is down to do all the drugs all of the time despite not appearing to be so inclined. May have taken meth one time but you would never be able to tell by simply looking. Always the last one to crash out at parties despite usually being the one to consume the most drugs.
Turns out (blank) is an absolute fucking trashboat, last night I saw them drop acid after drinking 12 pints at the pub.
