I really wanted to go down on her last night, but when I got home she was in the middle of an assturbation session to the new Justin Timberlake video.

Get the assturbationmug. Masturbation restricted to the ass region. Usually performed by placing dildos, buttplugs, fingers, toothbrushes, or whatever else may be handy into the anal cavity. Lube is optional but highly recommended.
Suzy had never considered assturbation until she overheard Julie talking to Maria about shoving a 9 inch vibrator up her ass while fantasizing about Tom (Suzys dad).

Get the assturbatemug. When someone is bothering you, on purpose, and won't leave you alone when you are trying to get something done, they are assturbing you. As in, they are disturbing you, and being an ass about it.
