Pre-curser 

Someone who is watching a baseball game and starts cursing at the hitter thinking the ball is going to be caught deep in center field but it actually keeps going and is in a home run.

Watching the Red Sox game Amy started cursing out Youk when she though he was going to fly out but he actually hit a home run. She's such a pre-curser.

precursery examination 

An assortment of inspections and tests that a pediatrician and/or child psychologist performs on a toddler during the time when he's just learning to talk, in order to determine the likelihood that he will develop a "potty mouth".

A precursery examination is all well and good, but I think that a physician should also check on how the child's PARENTS AND SIBLINGS "behave themselves" verbally, as well --- whether or not THEY exhibit a perpetually "salty" vocabulary is often a much-better indication of whether Little Junior is going to begin acquiring a "colorful" vocabulary than the results of any physical/medical tests!
