You go ahead and come of with the ones for the Dems. Here's where with drink when trump says:
....drinking game. My words are Leftist, lying, Biden and media. I should be shitfaced by the end of the first fifteen minutes.

Too many to be a good game.
I'd say, for Trump:
Uses some superlative repeatedly (Best, better, greatest,) all in the same sentence.
Mentions, Iraq, Venezuela, or Ukraine. Mentions more than one in a sentence take shot for each.
Talks about buying Greenland, Canada, etc. Must include some reference to money
Says ICE is doing a great job.
Trash talks California, New York, Illinois, or Minnesota.
Tariffs are working great etc.
Democrats:
Standing and shouting at Trump--Profanities take two shots
Using protest signs, paddles etc.
Refusing to clap for something obviously nobody wouldn't clap for like say, a veteran or someone Trump points out in audience.
Doing something in lockstep to protest Trump. Example, all refuse to stand for something you normally would stand for.
Making silly faces or gestures and getting caught on camera
