When a penis is placed under an armpit and the receiver moves there arm up and down like they are ringing a bell for a choo choo train.
This reminds me of my fourth grade camping trip when Mr. Hitchens broke into my tent, forced his cock under my arm, an ordered me to give him, an Armpit choo choo.

When someone is either on a roll with whitty come-backs or there on a roll with horrible come-backs.

The act of self-destruction despite repeated attempts by friends to intercede on the kisser's behalf. Sometimes it seems as if they just want to stand in front of the charging locomotive and get what's coming.
Mike, you know I'll back you up, but if you keep making trouble where there isn't any,and drag ME into it, no less, I'm going to simply allow you to kiss the choo choo. Kissing the choo choo is what you seem to want. Oh well...
