When someone uses teeth during oral sex and leaves visible marks.

Wow, that girl gave me a truckstop signature last night!

moist signature

When you have to sign on paper, in ink, not just do an e-signature. A "real" signature.

You have to take that document to a notary and get a moist signature.
I gotta get a moist signature on that contract.

Signature Shirt

A signature shirt or sig shirt or SS is a shirt that a person in a picture wears usually on purpose. This is sometimes a person's ow custom shirt but mostly it's not. These are usually validated by a myspace whore or a just a man/woman looking for a hot date. sometimes it cld be just a bikini top (hopefully only for a girl)
