look up any word, like snitch bitch:
 
1.
a fast-paced, relatively new sport invented by 4 citizens from Manchester, New Hampshire. the sport is played by the following rules and regulations.1. get a skateboard and a motor-vehicle. 2. ride the skateboard behind the back of a car or SUV, preferrably a Jeep™, using a tow cable or bungee cord ( either one is adequate). typically with 3 people: 1 driver and 2 stitchers. or 4 people: 1 driver, 2 stitchers, and 1 cameraman. although there are no documented attempts at this rapidly growing sport, it is a sport nonetheless.
Dude, i had such an awesome time stitching yesterday even though my neighbors told my parents that i was driving without a license.

or

Remember that time last summer when we went stitching and i fell off the board when we were going down a hill doing 40 m.p.h. and i got those huge gashes all on my whole right side.

2.
To put so much tobacco in a toot or drop-bong that it is impossible to pop, rendering the hit useless. Also, from this, to generally mess up something for yourself or someone else.
"Oh man, I stitched the bong"
