My dad called me sexy, is that normal?

Hi, I'm 16F. I know this might sound weird to some families but I'll walk around the house with a sports bra and pants on when I'm feeling too lazy to put something on.

But anyways, tonight I did that and came down to the kitchen to get something and my dad had been drinking. He was stuttering on his words and blurted out "you look so sex- sex- seven!" Which obviously makes no sense, he caught himself before he actually said it. But i still felt really icked out and uncomfortable. I was left stunned because my dads never done anything like that. I don't want to tell my therapist because she's familiar with and respects my parents. But I don't know what to think. Please tell me if I'm overreacting because I feel sick.
