1) The Basketball Dunker
This person has their arm up, hand cocked down, and waving it up and down. 2 points!
2) The "Teacher, I Know the Answer" Waver
One arm up in the air. They may be waving it up and down as if to get attention. In that case, they are The "Teacher, I Really Really Know the Answer! Please Call On Me!" Waver.
3) The Raise the Roofer
Two hands up, vigorously pumping them up and down. This may or may not be in time with the music. We don't all have rhythm. This person is really in agreement with what they hear.
4) The Rocker
What else? Fist held high. Triumphantly.
5) The Tray Holder
This person may be too timid to actually raise their hands in front of people. They have both hands at waist-level, hands upturned as if carrying a tray.
6) The Air Traffic Controller
This person is so into the music, they have forgotten all about the people beside them who have had to duck out of the way. They have both arms up and spread out to the side. Depending on how high they have their hands, either their neighbor's view has been blocked, or they have been clotheslined.
7) The "You You You" Pointer
Obviously this person is just pointing up in the air repeatedly, as if reminding God that they are singing to Him or about Him.
And just so you know, I DID listen to the music and the message. I'm not a complete heathen. So don't judge. But Christians can laugh at themselves once in a while too.
