Transdeuce

When "dropping a deuce" on an international flight.

While I was on my way to England from the U.S., the airport cafe food was slowly making its way down my intestinal tract. As a result, I dropped a transdeuce in the airplane toilet.

Transdeucer

When an man wearing normal male clothing enters the women's rest room to take a number 2, because either the mens restoom is occupied for way too long of a duration or out of order all together.

Scarlet became a tad bit uncomfortable on her break when the toilet stall next to hers suddenly slammed open with a bang, and in walked in an obvious transdeucer who began deficate quickly wearing size 12 and 1/2 Redwing workboots that were visible to her from the opening under the stall.
