Mother I'd Resort to F*cking. To be used in a situation where you wouldn't necessarily LOVE to bang this chick, but you wouldn't entirely dismiss the notion. Usually a single parent co-worker with 1-2 children, who never stop talking about their kids while you're thinking "...eh i'd plug this chick."
Female: "..so OMG, the other day, in quilting class, we started using pink fabric and OMG it was so cute you should have seen {insert child's name} he/she LOVED it!"
Male: *Thinking* 'I probably would stick it to this person. I wouldn't quite give her MILF status, but I'm willing to go MIRF'
Male: *speaking* "oh no shit, that's awesome"

Get the mirfmug. by Bree & Jake - Nerds March 8, 2009
Get the MIRFmug. A MIRF is the exact opposite of a milf. While a milf is a mother that someone would like fuck( bang the shit out of) a mirf is a mother that someone would regret fucking( really bad pussy haha.)
juliets mom is fucking hot and is definetly a milf. but john's mom is a mirf. I totally regret fucking her, her pussy smelled like rotten fish and dam did she need to shave or what.
