I hate one upers, I also say my car is stock, I will always say that because I dont need them asking questions and dont need to here the BS of somthing els they are making up. I work with 2 one uppers and It can get very annoying fast. the kid tels me he has a stock ranchero that runs 10's in the 1/4, Then I ask him about it a month later and he denies it, and is like "Not me, I was talking about my friends honda civic" lol Im like yeah right, So I made a little BS flag, When they talk Ill go over to my tool box and grab it and start waving it around just to piss them off. 


Be cool, remember you're not driving a rice burner.
