noun. The act of biting off your fingernails and taking them and shoving them deep inside your penis, then masturbating ravenously. The jagged edges of the bitten-off nails will inevitably cut up and slice your urethral tract. When your are about to reach climax, you call your significant other over and then cum into their mouth. The mixture of blood and semen will resemble a Strawberry Sundae, while of course the fingernails will represent the shredded nuts on a Sundae.
