Slash and Dash 

a fantastic game to play when drunk in a road/town you dont live in; the game starts by ringing the doorbell, then as quickly as possible take a 'slash' or 'piss' on the doorstep. if you can finish before someone answers the door, you win! if not, good luck explaining what you were doing.

splash and dash 

This bold move of sophistication occurs when one has become so in tune with their body's bowel movements that they know exactly when a "no-wipe needed" poo has occurred and they get up from pooping without even a "prove-it wipe". Many have wanted to try this power move but have not the stones to dash without a "prove-it wipe". This classy move was originated by Grant Habbershon, a young socialite from Boston who spent 6 months perfecting the move by tweaking his diet and hydration status.

Man, that Terrance used to have such a hard time getting a date but after he perfected the splash and dash he has the confidence of a Bradley Pitt and the women just love him.
