Based

Slang: Agreement with a regressive opinion to try to fit in with a crowd. Could be read as short for 'Based on conformity'. The polar opposite of punk.

May have had a different slang definition originally, but this has what it has become through online usage.

Punk:

Living your life your own way giving no fucks what people think = That's punk.

"Based":
Moron 1: ""Hitler had the right idea""

Moron 2: "That's based, bro."
