look up any word, like donkey punch:
 
1.
The act of hitting on a drunk girl in a local bar and trying to get her to go home with you. After step 1 is successful, you then begin to hammer the chick so hard until she not only has NO recollection of that night, but the night before as well, thus ending all possibilities she remembers you and wants to "get to know you better."
Ryan: Dude I totally Hit and Hammered Steph last night!

Jeff: Thats fucked! It was her birthday 2 days ago!
