you're minding your business, just, spending time by yourself, when a short blue haired person comes up to you

BF: "Beep Bep!" Translation: (Rap battle!!)

He seems to want to rap with you, as he had a microphone in his hand....and his girlfriend is sitting on a giant stereo speaker set between you two to the side...

[Would you like to give a self description before we continue?]
