Since we can't be like "able-anal-ed" folks and "take a dump," we need a saying of our own. "Draining the bag" just doesn't cut it. Some candidates to consider:
Trapshooting. Has a nice ring to it. Imagine: "Hey Sally, back in a jiffy... gotta do a little trapshooting."
Turboturd. For the ostomate in a hurry.
Dash-of-splash. Similar to turboturd, but with some recoil.
Easysqueeze. When you know it's gonna escape quick.
Vulcan velcro release. OK... a little unwieldy... but a possible hit with
Star Trek fans. Possible scenario:
Captain Kirk: "Spock, take the helm."
Spock: "What's the matter with you?"
Kirk: "Gotta do some Vulcan velcro release. It's Scotty's damn warp chili again."
Spock, rubs chin: "Interesting."
Let 'er rip, then drip. For those days when you wonder, "Why did I get out of bed?"
And my personal favorite:
Blazing Saddles. (with apologies to Mel).
