An individual who can always see through the bullshit. Particular people who don't like sugar coating or pussyfooting and/or beating around the bush. A person who takes their own inventory before taking anyone else's.

Male RMF: a proud solid man, one whom has the most sensitive bullshitometer.

Female RMF: a bitch who is down to go ham on yo girl when she acting a hoe round her mans.
Remember how that dude Barret always was genuine and his own brand, that dude was a RMF (Real Mother Fucker)

Get the RMF (Real Mother Fucker) mug.
Genetic real son and mother do piv. son then becomes a real mother fucker.
Real as it can be, never actually seen a RMF (Real Mother Fucker); just like they say, inscrutable, volatile, a bit tricky to deal with.

Acronym for Resting Mischief Face. It’s like RBF, but the person with RMF has the unintentional countenance of one who is perpetually plotting Shenanigans. The RMF will typically intensify when the bearer is questioned as to the nature of the Shenanigans.

Much like those who possess the more widely known RBF, those with RMF are known to protest “It’s just my face!” Also, similar to the RBF, quite often, it’s not just their face.
The wry smirk was evident from across the room. “What are you up to over there? I can see it plainly written across your face- you’re definitely up to something.”
“No! I swear! It’s this damn RMF, I’m not scheming at all!”
