Well, actually, yes, though not in the fashion you describe.
Let me lay out the scene for you. It's a fairly peaceful day in the trailer park I used to live in, I'm in the little park area that has some old wooden swing/slide sets in it, right? One of my old friends, name of James, he lived right next to the park area, is chillin' with me, and we're about to go over to his house to play some Resident Evil (we used to trade off the controller every time one of us died). We hear this kid, big kid, name of Brent Seargent (giving you his last name 'cause I don't care if you troll the fuck out of the shithead), riding his bike past the park. Well, he and I have never gotten along, mostly because I was a scrawny kid and he was a vicious bully, and he decided that today is "Beat Ryan Senseless Day" for no reason (I used to occasionally torment him because he was an idiot and I have little patience with his type, so some of the mild beatings I received prior to this were deserved.). Well, James is no bigger than I am at this point, so he splits to get his 'rents, but before he gets to his house, Brent grabs me and slings me into the side of one of the slides, sending me toppling heels over head onto my ass. He comes around and makes to stomp on me.
Let me pause for a moment here to explain my adrenaline response. I have a very strange adrenal gland, it sends hormones to my brain and increases the rate at which I process information (that's the way I understand it anyway) and sends endorphins(sp.?) throughout my body giving me immense stamina. Also, I don't fight like other people fight. I fight to kill my opponent in as painful a fashion as I can when I lose it. I break limbs as painfully as possible and maintain my grip on them. I keep hitting after hitting has done what it needs to do.
So Brent has his foot over my chest ready to start grinding me into the ground, James is still a hundred yards from his house and I'm on the ground. I grabbed his foot and, as I stood up, brought it with me so I'm behind him with the heel of his foot touching his rear-end. I kick him in the other knee to bring his head down to my level and tell him in the most threatening tone a ten-year-old can muster when speaking to a twelve-year-old twice his size that if he ever fucks with me again, I will break his legs.
He left me alone after that. You may feel my reaction was over the top, but I never fully lost it, even though he had been torturing me for five years at that point and I had a lot of rage at him boiling up. I can actually feel a bit of bile rising in my throat just typing this. I haven't seen this kid for almost seven years and I'm still pissed as hell at him. He made my life there hell until I proved to him that I could stand up for myself and I could do it better than he could bully me.
So yeah, that's the closest I've ever come to completely losing it. There's a long history of mild psychosis in the males of my family, so I keep myself on a pretty tight leash now.
