jack and jill

Jack and Jill party: a gathering of males and females, who masturbate in front of each other for mutual stimulation and enjoyment. (Generally looking is encouraged but touching is not.)

From jack and jill, with reference to the nursery rhyme Jack and Jill.

Last weekend my wife and I went to a Jack and Jill party.

Jill

She has this natural swag and she isn't even trying. When she walks into a room every body stops and stares in awe.
On top of all that she has also a great personality, very social and musically inclined. Her interests are extremely broad which makes her even more to die for.

Everyone should at least have one Jill in his/her life.
You won't regret it.

I love me some Jill.
Look man, I bet here name's "Jill"!
Man, there should be more Jill's in this world.

JILL TILL

The female version of wank bank - A conscious thought by females to mentally photograph a person so as to be able to masturbate or jill off while thinking about them at a later date. Jill off is the female version of jack off: unassisted autoerotic stimulation.

"That dude is seriously hot!"

"Yeah, I might put him in the jill till"
