Optical Asslusion

When ones gluteus maximus appears to be rotund but when a closer look is taken, it is actually taking the affect of an ass but no ass is found until further investigation is taken and the ass begins much lower.
The "Optical Asslusion" Looks good from far, far from good.

assplosion 

The condition of the urgent need of a toilet because of upcoming mass defecation. The large intestine usually builds in gas pressure repeatedly, then fortunately subsides as you drive around looking for the best fast food restaurant to rush the restroom. As you park, the inevitable last build throws you from the car, you burst into a stall, and you barely drop your pants in time before the assplosion occurs. If your ass does not create a seal with the seat, the assplosion produces colorful feces all around the stall including walls, toilet, floor, and sometimes ceiling. Strangely, the toilet paper is untouched so you are able to make a clean getaway and vow never to return to that establishment. It makes for a good story every time you pass another similar restaurant.

Surf Dracula Syndrome 

A phenomenon in film/television series, most notably streaming series, where the main premise is drawn out to such a point that it takes an entire season or more to get the parts of the series the audience is actually interested in seeing.

For example, if a series is titled "Surf Dracula," a majority of viewers would tune in expecting to see Dracula surfing by the first or second episode. However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
I watched "Smallville" on Netflix the other day. Dude, it was ten seasons of filler before he finally flew! Major Surf Dracula Syndrome!
