The name provided to those who dont refuel the company car, failing abide by the half tank rule, despite having an abundence of time on a nightshift to refuel!
Kris was nightshift last night driving about in the company car and failed to refuel when it reached half a tank to the detriment of his colleagues. Kris is therefore a "half tank wank"

Self masterbation (usually male) performed simultaniously whilst inserting a finger into the anus and asphixiating ones self, but not beyond the point of passing out. Only enough to reduce the amount of blood flow to the brain so that it is directed towards the penis for a more intense wank.
Tying a belt or a tie to a hook or bar and then putting it around your neck , lean into it to reduce circulation to the head, shove a finger up your butt and away you go, thats having a chokey pokey bum wank!
