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"
