The full form of FUCK is Foxtrot Uniform Charlie Kilo.

“Foxtrot Uniform Charlie Kilo” is a song by American alternative rock band Bloodhound Gang. It was released as the lead single from their fourth studio album Hefty Fine. The song was written by band members Jimmy Pop and Jared Hasselhoff. 

The lead single off of 2005’s Hefty Fine is riddled with sexual innuendo. Even the song’s title uses the NATO phonetic alphabet to spell out the word ‘fuck’.

The song’s lyrics originated from the singer Jimmy Pop and bassist Evil Jared writing emails containing innuendos to each other.

[Intro]
Fish don’t fry in the kitchen

[Verse 1]
Vulcanize the whoopee stick in the ham wallet
Cattle prod the oyster ditch with the lap rocket
Batter dip the cranny ax in the gut locker
Retrofit the pudding hatch, ooh, la, la – with the boink swatter

[Pre-Chorus]
If I get you in the loop when I
Make a point to be straight with you then
In lieu of the innuendo in the end know my intent though
I Brazilian wax poetic so hypothetically
I don’t wanna beat around the bush

[Chorus]
Foxtrot Uniform Charlie Kilo
Foxtrot Uniform Charlie Kilo

[Verse 2]
Marinate the nether rod in the squish mitten
Power drill the yippee bog with the dude piston
Pressure wash the quiver bone in the bitch wrinkle
Cannonball the fiddle cove, ooh, la, la – with the pork steeple
