To bang a woman during the summer, preferably on a beach. A reference to the musical Grease.

Get the summer lovin' mug.
When while working out of town with a female co-worker who just so happens to be named Summer, you are forced to endure incessant crying about being homesick, missing her puppy/boyfriend, stress of everyday life, etc, but as a reward get to achieve your lifelong quest of pulling a Filthy Ricardo on her hoe ass when you encounter her sloppy drunk in the hotel lobby.
Had me some Summer Lovin' last night after I caught that hoe slippin' in the lobby.
