You had decided to mimic how Present Mic normally talked when he came over to confront you about you messing around in class.

The whole class burst out laughing while Mic did a double take.

Mic: "Did you-"

Denki: "THEY'RE ACTUALLY DOING YOUR VOICE."

He had to hold back a groan, a smirk appeared on his face when you mimicked him.

Mic: "First off, do not 'ya dig?' me-" He said, trying not to laugh.

Mic: "Second off, this is a school, you can not just be calling people 'hotties' just because you're dating them." He said with a playful tone while keeping up that stern glare.
