Grantasy

A man in his mid to late 20's who thinks about and sometimes sleeps with 14 year old girls

"Wow that chick was hot"
"She looks 14 dude"
"Man i totally just had a Grantasy."

A fetish where a younger man fantasises about a GILF, a Grandmother or a woman who is old enough to be a grandmother but is also attractive.

Look at that woman (50 years old), she is my ultimate grantasy.
