nemestreet 

A lightly-trafficked cross street that always holds you up with a red light - often one which takes FOREVER to turn green.

I'd have made it on time to my waxing were it not for my nemestreet. Willoughby Avenue parked me for what seemed like five minutes and not one car or pedestrian crossed the intersection!

Nemeses 

Plural form of nemesis, meanig enemies or rivals. Can also be used after "arch-", meaning that someone/something is your worst enemy.

Not to be confused with "nemesi", which is not an actual word.

Rich and Don are my nemeses, because everywhere I go those two are always one-upping me.
