Greasy Drew
Greasy Drew (n,adj) : an Andrew that only comes alive on the weekend. This state of grease typically comes after a bit of alcohol and can be noticed through actions such as slurring his words, or getting a bit handsy with the gender of his choice. A greasy drew is often seen studying hard during the week and blacking out on the weekend.
I always thought Andrew was such a nerd, but after seeing him last weekend I know that he is just a Greasy Drew.
