Retarded Mongoloid Fuck. A name to someone who has done something completely stupid and should be slandered by this particular phrase. This is only used in EXTREME cases!

A rich mother fucker. This is a individual who makes over $100,000 per year and holds substantial assets. They are also in short referred to as a "RMF". These individuals are traditionally the least charitable and the most frugal.
"Hey Jon, I am doing the personal taxes for this 'RMF', look at how much this fucking guy makes! And to boot, he only contributed $5 in donations to charity for last year! What a piece of shit!"

RMF is an abreviation to a spanish phrase that says "Riéndome muy Fuerte" it was invented because LOL has some time here and in spanish it almost doesn't makes any sense and sounds stupid.

Resting Mom Face RMF. Similar to Resting Bitch Face, but exaggerated by the sheer over tired zombie like nature of a mother. The years of interrupted sleep, repeatedly asking they boys not to fart at the table, and giving ‘the look’ when we were in public had rapidly increased the severity of my previous RBF diagnosis. I was told that prolonged exposure to being ignored, hearing ones name on repeat, stepping on LEGOs in the dark, and constantly walking into a bathroom where the TP roll has not been replaced can increase your risk of serious Resting Mom Face.

TJ looked at Patti and couldn't help but notice she had Resting Mom Face RMF. No matter what he said all she would do is look back at him with RMF
