ball tap 

To painfully hit someone in the balls by the flick of the wrist and laugh on their behalf or roll on the ground if it is done to you.

I had 3 friend who were spending the night for 2 weeks while my parents were gone. They gave me a wedgie and pulled my boxers over my head. Every time I tried to pick it out they would hold me down and would each ball tap me 100 times. (I never got the wedgie out for the entire two weeks and I counted I was ball taped a total of 15,900 times).

Pink Tap 

Someone who goes to beer fests, beer-bar openings, and other craft beer promoting events, and spends the night drinking bud light or blue moon. Basically wants to seem cool by attending said events, but probably couldn't tell you what a Saison is or name a stout other than Guinness. Similar to a "Pink Hat" but craft beer related.

At the latest beer festival, featuring 1,000 brews from 200 awesome craft brewers:

Guy 1: Hey man, you see that dude over there getting his third sample of the summer wheat? They have an Aged Imperial IPA for chrissakes!
Guy 2: What a pink tap. He's the reason these things are overcrowded.
