2.
The feeling you get when one is either embarrassed or someone has challenged him/ her to something. You can recognize cold blood by feeling the blood run through your veins. It feels cold for whatever reason and your face gets red & hot.
Greg: I got such cold blood yesterday when Ray challenged me to step up and fight him, but when i did the right thing and declined, i got it even worse from the embarrassment.

Timmy: That sucks ass.

Greg: Yep.
