Somebody told me
Are you playing thick or just are?
in the middle of a conversation. and I didn't know its meaning. I searched for "play thick" in Google, but I didn't find anything.
- Is “are you playing thick” slang?
- What does it mean?
I think here playing thick refers to 'pretending to be fool', so the the person is asking, "are you pretending to be a fool, or are you a fool?"
- Informal Lacking mental agility; stupid.
