You done f***ed up Thanks!

I don't believe Fred fucks anyone. His ascot is actually a promise for chastity

There’s an episode where Scooby catches Shaggy and Velma kissing and is seriously affronted. So... take from that what you will.

There’s also a valentines episode where the boys live together and the girls live together. Another where Fred tells a person the only people who call him Freddie are those he dates and then in that episode on Shaggy calls him Freddie
