Grandmother I'd like to fuck and the daughter of GGMILF, the great grandmother I'd like to fuck.

My wife is a 57 year old GMILF and the grandmother of two but she looks 35 and gets hit on way too often. . .she's a dental hygienist!

Grand Ma I'd Like to Fuck.
A spin off word from the term MILF (Mom/Mother I'd Like to Fuck).

Although less common, a GMILF often is more exciting than a standard MILF.

Jenna and her mom are okay looking, but it's granny who's REALLY hot. She's such a GMILF.

Grandmother is one word, so that means that a 'Grandmother I'd Like to Fuck' is just GILF, not GMILF.

"Check out that GMILF."
"What the fuck are you trippin' on cunt, its GILF, bitch."
