Poop Blocker

That person who brazenly cuts in front of you in line for the bathroom, fully aware of your urgent intestinal plight. It's as if they take pleasure in your discomfort, making their act all the more infuriating.

"Honey, please don’t be a poop blocker when we get home. I’m crowning and it won't wait."

hormone blockers

Hormone blockers, also known in some contexts as puberty blockers, are used by transsexuals to block various sex hormones. For instance spironolactone, a diuretic, is often prescribed to male-to-female transgender persons to block androgens or male hormones.

A hormone replacement therapy (HRT) regimen usually consists of at least two prescription drugs: hormone blockers to block the original hormones, plus a new, replacement hormone in the desired gender. For instance, an M2F transgender patient may be given spironolactone to block male hormones (androgens, testosterone) plus a female hormone such as estrogen (Premarin, a drug made from pregnant mares' urine, for example).

Once the original genitals (testicles or ovaries) are removed, the blocker is discontinued, leaving just the hormone replacement.

Her intention is to block your battle plan, thus preserving the apparent chastity of your target -- or in this day 'n' age -- preserving the lady's opportunity for her own not-so-pious intentions.

During a splendid evening of ice skating, and Just after I had copped a really awesome 'fee'" as well as the mother of all sloppy smooches, her roommate shows up and wants to leave early. So I bellow at the top of my lungs: YOU GODDAMN COCK BLOCKER!!1

Lead Blocker

When someone has a tooth that seemingly grows in front of a row of teeth in an obtrusive and obvious way. Generally the misplaced teeth are so unsightly it comes as a shock when the person's mouth opens. Jewels teeth are a mild example.

That chick was hot, but when she smiled she totally had a lead blocker.
