A term playing off of MILF (Mother I'd Like to Fuck) except the G stands for one of many things: Grandmother, Grandfather, Girl, or Guy. As such it can be used as a gender neutral term.
"Damn that dude is such a GILF, I'd pay money for a piece of that change"
OR
"Holy shit that old lady must bathe in the fountain of youth, totally a GILF"

Get the GILFmug. When you find out that you're a brand new grandmother. But you or your son (a daughter would know) didn't even know your grandchild even existed. The baby mama either knew it or didn't know, but the fact remains: you got Gilfed.
Brand New Grandma: I just found out my son has a daughter.
Online (& soon to be Offline) Friend: You just got Gilfed.

OMG did you see that Great GILF pushing her walker? She was so hot the way she was breathing hard. I couldn't help but fantasize that she was panting all over my body.
