It's a good thing the word "Gross" exists. Otherwise, a tsundere would have almost nothing to say to any and every male.
Edit: and "Perv." Perv and Gross... Gross and Perv. Armed with those two words a tsundere ... wait a second! That's his wife. So, a guy wanting to kiss his wife ... is a perv?
Japanese culture will never cease to amaze me. *sighs*
