when guys take out their erect penises and lay them on a tailgate to measure who has the bigger penis.
Lastnight Jim, Tony, and I had a tailgate test. Jim ended up having the biggest penis. Tony and I have the same size penis. Hey, atleast we tied for last!

The first child in a mother and father's relationship. They are the ones that have the roughest time usually, and are used as a little test run to become a better parent overall. They're usually the child that the parents go hardest on, and in worse parents, it'll stay that way.
Person 1: "We should have children!
Person 2: "Yes, definitely!"
Person 3: "Don't, you have no experience, you'll create a test child."
