What is Mexican Dipstick?
1.
A knife. Termed "Mexican Dipstick" due to the amount of Mexicans (mainly those in gangs) who typically wield knives.
Primary function is to determine if the person it is tested on (victim) is low on oil (blood). A play on the "real" dipstick, used to measure oil.
So I was walking to the 7-11 and some guy was like "Tennis Rules!" so I responded with "Tennis is for bitches!". He proceded to pull out his mexican dipstick and chase me for 2 blocks before he gave up.
