Kissing mouse

We were learning a song about a mouse and some stolen food in pedagogy class and there was a line that goes チューチューチュー (chuu chuu chuu = the squeak squeak squeak a mouse makes).

"chuu" also happens to be the slang for "kiss". Being bored by the whole thing, I said "chuu shite" (kiss me) to shou-kun seated beside me.

The girl in front turned back and looked at me in horror.

Never had I felt the need to explain myself until now.

"He's not my type!"
