Pentillion

The fifth power of a thousand, i.e. 10^15, as opposed to a short-scale quintillion which, irrationally, is the sixth power of a thousand, i.e. 10^18, and a long-scale quisntillion which is the fifth power of a million, i.e. 10^30. "Pentillion" belongs to a consistent system for naming large numbers proposed in 2001 by a member of the University of North Carolina.

The object which you see through the telescope is a pentillion miles away.

Penta-date

When a almost-dating couple drags three of their friends to "hang out", which really means the three non-dating friends get to just sit and watch the couple deep in conversation with eachother.

Other activities can be long hours at a bookstore, and being serenaded at a park by musical homeless (but talented) men. The two have their date on the backs of three poor, bored to death friends, equalling 5(pent)people.

Tridate, aka thrid wheel, also sucks, as well as quada-date.

"hey Brit and Brad, i am so sick of hanging at this bookstore for 3 hours while Mark and Marsha discuss the meaning of Neo-commercialism in the post-pseudo-elitist world. I feel like i am on a penta-date"- Shayna

Penthouse

The larger, more spacious handicapped stall in public restrooms. It sees the most traffic, and therefore is more prone to horrible messes.

"Hey Steve, go clean the men's penthouse, it's filthy."
"No, no I'm not doing that again."
"C'mon..."
"No, never again, never again."
