An alt-right "snowflake."
Typically a coward in person, a bully in internet forums. Usually white/Caucasian, under educated, and angry. Has a propensity to use caps lock, change the subject when presented with verifiable facts, and post "fake news" as a response to anything with which he doesn't agree.

The yellow snowflake posted, "FAKE NEWS!" because he didn't read or understand the article but he disagreed with the headline.

yellow cake 

Really potent cocaine with a yellow color and sticky texture, with very high potency.

Cooking this kind of coke to crack will yield at least a 90% return by weight.

I got some yellow cake the other day, and the shit was sticking to my mirror and blade, I could barely sniff it, but it didnt take much at all!!

yellow hammer 

A person of the trades (auto mechanic, carpenter, plumber) who knows virtually everything about his particular line of work, but little to nothing about anything else. This can include life itself. While not considered a derogatory term by any means, it *implies* said person would do well my expanding their horizons.

Darn this carburetor! I can't figure it out. I gotta call yellow hammer over and have him take a look at it.
