To tickle someone with the tip of your penis. Tipple.
Yeah man, I tippled my girlfriends armpits last night. She loved it.
When your lower belly aches, you feel a sudden hot rush to your butthole but can't get to the shitter anytime soon. The sweats kick in and you're forced to wait in pure agony until the feeling passes.
Man, that mexican from last night really gave me the poop sweats.
