Never go full Army

I was out and about at a grocery store, sporting an awesome Oregon Ducks shirt, when I was approached by a guy I didn’t know

Random guy: Are they going to win today?

I don’t know what possessed me, but I went full Army on him (never go full Army)

Me: (practically yelling) HOOAH!

He was visibly taken aback by my outburst – I believe he thought I very aggressively asked “who?”

Random guy: th… the ducks…

Me: Oh, right, yeah totally!

I gave him a thumbs up as he walked away, looking both confused and slightly alarmed
