Invented in the mid 90 as a by-product of the handjob, a
sexual favor in which a man's penis is manually
stimulated by another person using only their left hand upside down aka "a backwards
lefty"
A friend of mine asked me to stop at the bank and deposit some money for him, so I said I'd
make the deposit in exchange for a Wade Boggs on
Tuesday night and he counter-offered me a hand
gallop on Wednesday, which I happily accepted.
