Someone who is upper class and also a bit of a pothead.

They are likely to have bought their cannabis with pocket money, and often smoke it at fancy house parties.
You wanna go to Sebastian’s party tonight? I’ve heard he’s a bit of a poshhead.

Get the Poshhead mug.
n.) One who smokes an alternative herb to cannabis called Posh. It may sometimes be found in your local 'Smoke N' Save'.
Example 1:
A:) Yo man, I just went to Smoke N' Save and got some of that Posh stuff you were talking about. One gram of it.

B:) Yeah, just be careful with that stuff, dude. I started on it the other week and turned into a poshhead real quick-like.
