The act of checking a man's masculinity by crying out "MAN CHECK!" then immediately kicking the questioned man's ball sack. If asked why such an act was done, one responds "I found his lack of faith disturbing."
Tim: "Lisa really hasn't called me lately. I hope our relationship isn't in jeopardy"
Tom A: "MAN CHECK!!"
*swack!*
Tim: "What the hell man?!!"
Tom A: "I found your lack of faith disturbing. Grow a pair."
A man of culture is a person who understands a niche reference mostly about anime. A man of culture is also what most retarded teenagers overuse just because someone one has a sense of humor in the internet and their underdeveloped, stupid brains can't use their synapse properly to come up with a better reply other than "he's a man of culture".

Majority of the comments: Ah... I see you're a man of culture as well...
