You and the rest of the team were bored, and decided to go have some fun at a bar, with basically everyone except pyro drinking something. You never seemed like the drinking type to anyone on the team, but soldier challenged you to drink more then him in a minute. And you, being equally competitive as him, agreed. To put it simply, you won, but you also managed to get everyone on your team concerned since, you know, you drank like 10 alcoholic drinks in a minute. And they had the right to be, since on the walk back to the base, you were stumbling around and singing drunkenly like a damn fool as everyone else was basically babysitting you to make sure you didn't fall over or run off, since they all had no idea what you would be like drunk.
