Everyone got hit by a curse quirk including the teachers at UA. Class 1a was all in the dorm room saying their curses.

Bakugo: "I can't lie..."

Mineta: "I always have to tell the truth..."

Shoto: "I have to tell one secret to each person."

Izuku: "I always have to bake something everytime someone asks me for food."

Kirishima: "My quirk is always activated."

Kirishima looks at you wondering what your curse is. "What's your curse?"
