PNFC: Please no fat chicks: Similar to an atheist, only a fatheist does not believe in fat chicks. Not even thick chicks. This results in him being a poor wingman, but reduces his odds of being crushed to death.
An intermediate level content warning, significantly worse than "E for Everyone" but not as bad as NSFW. pnfo is an anagram of "prolly not for the office."
Check out this YouTube of of a cat unhooking some chicks bra, you don't see any nips, but it's still pnfo.
