When you're on YouTube clicking one video after the next. Watching whatever looks interesting.
Friend: whoa you look like you haven't slept in days
You: that's because I haven't, I've been surfing the tube all night
Synonym for kissing. When lips touch during a kiss, the union creates an unbroken tube from one person's butthole, back though the mouth to the other butthole.
Hey baby, would you like to go to the drive in theater and do some butthole tubing?
When one lies naked in bed and proceeds to nut up in the air, quickly turns to then catch their own nut in their anus.
Person #1: Dude I was tube throwing last night and I can’t even shit this morning my anus is glued shut
Person #2: Yarks
In "touching tubes", two men touch the tips of their penises together then pull forward enough foreskin so that it covers both their penis heads, so the two penises now look like a single shaft connecting the two men's bodies.
That looks totally trippy-- and it sounds more than a bit romantic!-- but it is all totally no homo, because nobody's balls are touching.
If there's not enough loose foreskin (or just plain shaft skin) to cover both heads at once, then the two men are trying to touch tubes, but not quite managing it. However, that attempt still counts as "tip to tip", and a nice friendly sword fight can be the participation trophy.
Conversely, if there's there's a great deal of foreskin, then the men can even do full-on docking.
Comparing sizes can be a gateway drug to touching tubes-- which can immediately escalate to a non gay handjob, and from there, to anything.
"Me and my entirely platonic friend Kyle were comparing sizes, to address the question of 'grower' versus 'show-er'. Then hey yolo, so we decided to try touching tubes. I don't have much slack, but we did just fine, because he's got a glorious anteater! Then, in the spirit of wholesome friendship, we fell right into a bro job and cum swapping session that lasted for hours. But we wanted to clarify that this is no homo, so later we each gave each other a non gay handjob... several times... just to make sure we're totally straight."
Someone who can't ride on the train properly and keep on falling into other people.

Dude: Watch as I ride this train with no hands!
Friend: Why? You're just going to fall into me again, you're SUCH a Tube Noob
