Slippery dylsy

When one sticks their tongue inside their nan after she has been ejaculated in, usually by more than one sexual partner.

Slippery Dylan

The act of tongue punching your grandma, usually unexpectedly.

The other night I walked in on my sleeping grandma and I put my tongue in her anus, in other words I pulled off a "Slippery Dylan".
