I know for myself I have physical reactions like literally getting out of my seat. I remember I was sitting in a computer chair with my feet underneath the desk and when RDA landed that headkick on Shalarous, I tried standing up only ramming myself into the table.
I don't really yell or anything. I'll have things like Mike Pyle's spinning elbow that completely wakes me up, mouth and eyes open.
After seeing what Silva did to Forrest Griffin, I think that was the only time I had to run... oh no wait. Shogun vs. Hendo. I was literally doing shoulder rolls in my living room. And saying to myself "oh my god, oh my god". And after Korean Zombie vs. Dustin Poirer I was so pumped out. My buddy and I went full out sparring. I think he was pumped up to, cause he normally fights like he's Machida. But we were trading punches and kicks and I had my Shogun-Machida 2 moment, except I dropped him with a body kick.
Things get a little rowdier and louder if there's a group of people for sure. The excitement of the fight and the people I'm with, takes it to another level. It was highest during Sexyama-Leben and Overeem-Browne.
Both times when the fight ended. I don't know why. I let out a loud, "Motherfucker!"
Anyways... what are you like during/after fights? Do you jump out of your seat? Pace around? Some weird shit that I can't even think about (please I would really like to know no judging)? I have a friend who literally winces anytime a hard shot is landed. Watching an Edson Barboza leg kick massacre with him is the most annoying thing possible.
Living with roommates, I'm a lot quieter now, mostly face reactions and moderate "ohs, and ooohs".
