John Thumb

Defined as the act of releasing one’s bowels in a manner where the shape of said excrement perfectly fits into the bottom of said toilet, plugging up the hole well enough to prevent successful flushing. Similar to the tale of the boy holding back a leaking wall with his thumb, this unintentionally shaped turd plug seats itself tight enough to hamper draining of thy marble throne.

Once I was finally able to push out that brown submarine from my ass, the dam turdpedo clogged my toilet so bad that my plumber said he doesn’t respond to JOHN THUMB service calls.

Black Thumb

A Black Thumb is the male equivalent of a black widow. It's a toxic, narcissistic man who is poisonous to everyone he encounters, much like Henry the VIII. His heart is black as the underworld, and he's as attractive as a thumb, hence black thumb.

Her: Are you still dating Killian?

Me: That guy is a black thumb, I'm embarrassed I ever dated him.
