Used to make your piss pipe all moist while your stroking it like there's no tomorrow.

K-Y Jelly is a water-based, water-soluble personal lubricant produced by Johnson & Johnson. The initials "K-Y" are not known to represent any words — they were described by their originator as "arbitrary letters" — but are retained for their brand-identity. K-Y Jelly uses glycerin and hydroxyethyl cellulose as the lubricant. K-Y Jelly does not contain a spermicide.
My girlfriend has to quit having sex after about 15 minutes because her vagina starts to dry up, and it hurts her. So I used some KY Jelly to add moisture.

Something you put on your toast in Louisville, Lexington, Radcliff, and the rest of the Bluegrass State.
Ma: "Hey Pa you want some toast?"
Pa: "Yep, and don't forget the butter and KY Jelly"
