Bullhead city. Warmup with Coronas. Two friends and I set up 6 glasses of half and half rum and cokes but unbeknownst to me one of my friends added dry gin to each one of mine. I pounded two of the glasses one after the other and my throat killed. We finished all our glasses and then played indian poker. It got out of hand and one friend (the owner of the house we were staying at) started hiding alcohol and my other friend and I kept drinking our tall cups of rum and coke. The next day was hell, literally and figuratively. 120 degree heat and a hangover.
My high school story I previously still ranks higher because my gf at the time never let me hear the end of it and that pretty much ended that relationship because I got outta hand.
