2.
someone that rides a sitdown type PWC (couch). typically clueless and lazy with no athletic abilities. a coucher will typically block the launch ramp with their rig as they stage, instead of pulling to the side to free the ramp (proper etiquette). after launching, they will usually go wide open throttle from the ramp, sending a wake through a no wake zone, thus slamming other vessels into the dock. after zooming at full speed, they will go to the largest group of people they can find and raise their buttocks high in the air as to signal, "hey, look at me... im a coucher!"
"oh, geez... here we go... here come a flock of couchers. protect whats yours."

3.
A french -er verb meaning "to have sex". It was derived from the verb "se coucher" meaning "to go to bed" for non-sexual purposes.

The verb was popualrized by the song by Lady Marmalade with lyrics saying "Voulez-vous choucher avec moi? (Ce soir)" which is incorrect as far as grammar goes. The form is used in the polite form, indicating that the two people have never met.

Pronounced like "Koo-shay" and not "Kow-cher".
