tacwash
The mints that end up in your hand when you only wanted three or so, but the casing dispensed too many, so you put the excess mints back in even though they touched your hand.
Once an act of tacwash has been committed, the mint-dispensing casing should be clearly marked with the tacwasher's name so that the mint doesn't mistakenly touch someone else's hand (i.e. eww).
