The monthly ritual that everyone takes part in. Im refering to the hygenic applications like, washing your hair that one extra time, brushing your teeth extra long, flossing til the cows come home, trimming your nails, plucking those unwanted hairs.. the extra long shower.. or bath.. to get super clean squeecky.. just because..

When your vehicle is running poorly, one holds the throttlewide open to redline for a long period of time in hopes that it will fix it
Mexican#1: hey amigo, is your truck road worthy yet? I need a ride to the store for some tequilla?
Mexican#2: not yet. I tried giving it a Tijuana tuneup last night and I think it's running worse now
When bad mechanics, usually greasy italian guys, rev the shit out of your engine to try to fix a problem. Usually results in more damage.
Vito's not a real mechanic, all he does is give italian tuneups and say its fixed.

Italian Tuneup
Driving a vehicle (particularly the engine) hard for a few minutes, getting everything fully warmed up and loaded, for the purpose of improving its state of running. Has some theoretical and empirical validity to it (in certain cases, it does actually work), but it can also be an incompetent hackjob substitute for actual mechanical skills and effort (in these cases, it usually makes things worse).
An Italian tuneup is the machinery getting exercise.
That shadetree shop down the road was supposed to fix my engine, but all they did was go for an Italian tuneup, only to stuff it into a tree.
