Promiscuous + delicious.

Adjective used to describe a person who, while screamingly attractive, is known for his or her rather lax attitude towards romantic commitment.
Ex.1: Man, that Shelly is promisculicious; she scores every night!

Ex.2: Dan's been getting it on weekly for the last few months. The ladies must think he's promisculicious.
Get the promisculicious mug.
