The act of dropping one's pants around the ankles while standing. This is usually a precurser to mooning, pissing, or receiving a blow job.
This girl wanted me so bad when we left the bar, I dropped trow in the alley and she eagerly went down!

A trowel is a simple hand tool used to layer or “slot in” mortar between stones or bricks by a mason. While the spelling has changed, “drop trow” is long forgotten slang from the masonry trade meaning to immediately “drop the trowel”, stop working, and/or walk away from the job. The term was often used in reference to unionization and labor strikes in the 1880’s through the 1950’s in the United States.
I'm droppin' trow'-- I quit.
