Hang out with some close friends. Preferably a girl. Conversations are amazing on rolls (i think so anyway). There are some people that get hella horny, but 99% of the time I rolled I just wanted to hold my girl.
Fun things to do while rolling:
Play in the snow
Go in a pool/hot tub
Have someone put the tip of their tongue on the white of your eye (sounds weird, but it will blow your mind)
Backrubs!
If you like, or can even stand electronica. I recommend listening to LTJ Bukem and Bad Boy Bill
