Didonaning 

(V.) Sitting in front of a computer for hours on end, and immediately locking it upon the entrance of others.

My roommate is always didonaning whenever I come back to the room at night.

dildonating 

Using a dildo. Masturbating.

Kelly was dildonating her fat vag last night. Yeah, I saw it and it was really gross.
