In this iCarly episode, Sam tells the world that Freddie never kissed a girl (they were all like 13-14 at this time). It’s one of those episodes where you have to “read between the lines”. They were using kissing as a metaphor for having sex. Being an adult virgin is a very big deal, and it’ll ruin your social life if people find out. Some people like to have sex “just to get it over with”, and I think that’s what the iKiss episode was going for. Everyone bullying Freddie for not kissing a girl is actually the most realistic thing out of any Nick show or comedy.

And this goes for male or female: if you are a virgin in your 20s, you will get made fun of BY EVERYONE if they find out.
