sidepipe 

to wear dangerously tight pants in the fashion of 80's musicians and/or pro wrasslers; so that the shape of your manly genitalia show proud and true like the god zues descending mount olympus.

these slortchin muffukkka's flock to my sidepipe like the pulsing dispenser of the nectar of the heavens that it is. (haters eat a dick)

sidepipe 

The part of boobs that shows on pictures that are supposed to be sexy, but are really just kinda dumb, when you can see the side of a woman's breasts from behind or an angle that is mostly from the back.

"Look at this hot Whitesnake album cover, check out that sidepipe!"

Side-Pipe 

When an individual of the male persuasion in an institutional circumstance (i.e. work, school, etc.) becomes sexually aroused, due to thoughts of past sexual exploits; the subsequent tightening of the groin area, due to the constriction of pants upon the hardened member, produces a penile-angular shift, which is almost perfectly horizontal in form, and points towards either the left or right. Thus the moniker, Side-Pipe.

Mosieur LePajonais: What, pray tell, is that tubular formation protruding from the side of your pantaloons?

Herr Schmidt: Why, my good man, tis my side-pipe!

Sidepiece 

A woman whose one level above a jump off but always below the wife. A sidepiece must know her part. While he may meet your family. You will never meet his. A sidepiece is a women he will never commit to. A sidepiece will never be wife material only an easy fuck.

Mary, Teresa, Amanda, Kim, and Christina were my sidepiece.
