A wankbot is a person who is so eager to wank off himself and others around him that people refer to him as a wankbot because it's so mechanical and androidlike now.
A wankbot usually has really weird tendencies like goosestepping round rooms naked just to show off his penis and hope that others will drool over it.
"Wankbot, can I have a handjob?" "Yeah sure, after I finish this person off."
"Oi wankbot, stop wanking."
* A person for whom wanking has become a routine, automatic activity.
* A person whose idiodic behavior has become second nature.
is he in the can again? that dude is a total wankbot.
