Blue hotel 

A Blue Hotel is a hotel, motel , etc., that rents out a room for an hour at a time. Couples ( straight, gay, whatever) go there for quick, discrete sex. They then return to their routine family life. Some married and partnered couples go there just to get some privacy while having sex. Recall that in many places generations of people live in the same very small spaces where privacy is impossible. There are several other names for these hotels, which you can find elsewhere on UD or on Google. These hotels are common in most towns and large cities in both hemispheres.

The couple decided to go to a Blue Hotel to get some privacy and be more spontaneous, intimate and noisy during sex.

blue belle

A girl who is likely to give you blue balls sometimes without even trying. Sometimes trying too much. She’s classy though and only some know how dirty a mind she has. She’s sweet and harmless, but enjoys getting a rise out of you because you are safe. You don’t mind except for that ache you’re a left with when she walks away. Perfect girl to bring home to Mom and Dad.

Guy 1: Without a doubt that girl has the dirtiest mind I’ve ever heard.

Guy 2: Yep, she’s a real blue belle. Now, my dick is hard and she’s gone.

Guy 1: I know. Me, too!

Blue Nosed 

The point where you get to the point of sneezing, but just can't get the sweet relief of sneezing.
