driving the porcelain bus 

When you've had too much to drink, and you wind up with two hands on the opened toilet in a kneeling position puking your guts out.

Man am I exhausted! I drank too much and was driving the porcelian bus all night!

Driving the white bus 

To vomit-more precisely to vomit into a toilet.

After consuming the most of a case of beer, Chad ran to the bathromm where john caught him driving the white bus.

driving the tuna bus 

the act of performing oral sex on a woman;

Buses have large steering wheels that cause the driver to hold their arms outstretched and somewhat wide apart. This position is similar to the way you hold your arms when bending a woman's legs back to go down on her. Performing oral sex in this position is like driving a bus... the tuna bus.

My room mate walked in on me an my date when I was driving the tuna bus. She was so embarrassed.

Driving the Sus Bus 

When one is taking part in super sus activities…
Most commonly used in the video game Among Us (but also applicable IRL). When one is “driving the sus bus,” they are the sussest of all.

Dude 1: Red is in electric but not completing any tasks.😐
Dude 2: Yeah, he’s driving the sus bus!!!!

driving the big white bus 

Puking up your guts into the toilet bowl while holding on to the rim with both hands to prevent yourself from falling in, while the room spins around and around.

After the party last night I went home and started driving the big white bus.
