Wasting time, lazing around, procrastinating. When you're supposed to be somewhere, and you're late, you're dogfucking.
Note this definition has nothing to do with actually having sex with canines.
dogdocking is when instead of wiggling his tonker into a domestic female dog (like any normal person might do on a regular basis), some sick fucker of a man inserts his cock into the penile sheath of a MALE dog and frots till he sprots.
dog-owner: well, all mah bitches have come on heat at the same time, so looks alike i be dogdocking for nex few days.
non-dog owner: eeeeeuw. tmi.
