When you use the TouchTunes app to play a song that completely changes the vibe just as you're leaving. Is the bar full of old people? Play some death metal on your way out. Family-friendly place? Throw in some WAP or 2 Live Crew just as you find the exit

Me:"I'll just TouchTunes Cropdust this place and play 'WAP'. Let's get out of here"
