a.k.a. "The Gooey T."
It's more than just an erection. It's when a guy likes something so much he gets a little goo on the tip of his wang. A tiny wet spot in the boxers is a sure sign that a Goo Tip has recently made an appearance.
"Hell yeah Matt's mom is a roast. I get a Goo Tip just watching her make a peanut butter and jelly sandwich."
