A variation on the classic Icy Mike but with a festive "twist". (1) deposit feces on celophane. Ideally, one would want a fairly firm log-shaped crap (2) add semenal fluid (liberally) to feces for somewhat of a marbled affect (3) wrap entire piece up (while maintaining or creating log shape) (4) freeze (5) use to fuck, when appropriate.
My girlfriend Julia loved the Icy Mike so much, that I decided to step it up a notch and surprise her with a Jack Frost for the holidays.

Get the Jack Frost mug.
Cum that was expelled through masturbation, ie- "Jacking", and has not been cleaned up, allowing it to go shiny and slightly crisp, like cake frosting.

Typically found in teenagers bedrooms, although fully grown men that have wank addictions have been known to jack frost their carpet on a regular basis.
Danielle thought she had hit the jackpot with Steven. He was kind, considerate, and seemed to be very house proud. She relaxed happily on the sofa, thinking about how great her relationship was- until she noticed the Jack Frosting on one of the cushions.

When recieving a Blow Job, the man pulls his penis out of the womans mouth just before he ejaculates, and blows his load right onto her nose. If hes a good enough marksman, it should collect on the tip of her nose,and resemble a carrot nose, just like a snowman.
Man that Jack Frost I gave her last night looked so much like a carrot that you could practically eat it.
