when your time spent on marlincrawler.com is almost at a month
when you know when 1st gens changed head lights from round to sqare
when you try and talk all your buddys into getting rid of thier pile for a 4runner or pickup
when you get excited to wrench or fab or weld or hell fix something broken.
when you look on CL and someone is trying to sell a yota and they post the wrong year, and you say "its a 90 not an 89 dumbass"
