Big Tide Rush

a sex act in which the male will insert a Tide Pod into the anus of the partner, and proceed to insert the penis, thus rupturing the Tide Pod at the moment of ejaculation

this results in a "Rush" of Tide/ejaculate from the anus of the partner

Last night I hit her with the Big Tide Rush. My dick felt great but there was a huge mess to clean up. Luckily we already had detergent on the sheets.
