Fido lick 

When a girl smears her vagina in peanut butter, and then lets her dog lick it off.

Hey did you hear about the girl who got a Fido lick?

No, I'm not into that kind of stuff.

FIDO score 

How your four-legged waggy-tailed buddy measures up when viewed by da likes of Freddie Mac and Fannie Mae.

I made sure to properly train Rover in basic things like housebreaking and not chewing up things or maikng a mess with shaken water or jumping up on people, and so hopefully he should be fine if any doubtful landlords check his FIDO score when deciding whether he and I can move into an apartment.

Semper Fido

mutation from the Latin meaning "always a dog", always being a dog, always base and self-gratifying, always begging handout, freebees, sex, gratuities. Always "dogging it".

When Zeb related to ladies and friends in his base self-serving way he was "Semper Fido" - always doglike.

Hot fido 

Much like the admirable crowd-favorite Hot Karl this act is performed by one of the canine species. Feed your dog whatever it is you've noticed causes him/her to drop severe rank steamers and have it to lay one of these mammoths across your stomach, back, face. Whichever suits you.

Well last night Dexter and I got into some curry and before bed he let loose a nice Hot Fido on my chest
