Get the derpster mug.
A hipster who tries so hard to be hip that they act derpy all the time.
That guy wears plaid shirts with purple pants. What a derpster!

Get the derpster mug.
The type of person who dresses ironically or does other hipster related things but is too dumb to know the meaning of the word irony.
I'm buying this penny farthing because I saw someone else with one.

And it was cheap. Doesn't that make me a derpster?
