Baked Alaskan Pipeline 

When you have anal intercourse while using rubbing alcohol as lubricant. The giving party then takes a lighter and lights the receiving party's b-hole on fire.

Billy B's girl needed a skin graph after he gave her a Baked Alaskan Pipeline.

Cleaning the Pipes 

When you go into the bathroom and you end up taking a shit, pissing, and ending with a good ol' hearty fap.

"What the hell is he doing? He's been in the bathroom for 40 minutes."
"Prolly just cleaning the pipes"

Cleaning Out the Pipes 

1. Jacking off to dispose of excess cum (if it has been awhile since you last fucked) 2. Jacking off earlier in the day when you will be fucking a hot broad later (in order to last longer)

Since I was seeing Jessica later, I performed a Cleaning Out the Pipes!
