FLP

Flower Love Power is probably what this should mean but it instead usually is Finger Licking Good (due to KFC) and sometimes worse things but you probably already know that from other definitions if FLP on this page.

Polly: FLP is the best thing in the world!
John: Wait are you talking about KFC finger licking good?
Polly: No Flower and Love Power!
Phoenix: I was thinking of something totally different here…
