Jackstrapolate
A smelly mix of ‘jack off’ and ‘extrapolate.’ It’s when you imagine a hot young girl turning into a milf so you can cum like a dog.
He jackstrapolates her and now she’s a milf in his head.
I jackstrapolate my crush and now I get hard during lunch.
She jackstrapolates herself and now she’s a milf and I’m jealous.
