Chinese bullet train

An act of sex which often incurs two large breasted Asian women punching each testicle as one does with a speedbag in boxing

Bob: Hey Jim! I heard the Chinese Bullet Train you had last night was a wild time

Jim: Yeah for sure

"Thomas the Train" it

When you take a bong rip you can't finish, leave some stale smoke in the chimney, and clear the bong by blowing into the downstem.

After taking a massive bong rip I couldn't finish, I had to "Thomas the Train" it.

All you had to do is follow the damn train, CJ

This mission is quite easy if you are attentive

CJ: *loses those mfs*

Big smoke: All you had to do is follow the damn train, CJ
