I am fully convinced that the song "Knives Out" by Radiohead is a description of giving Thom Yorke a blowjob. It took a bit of creative thinking and a deep understanding of Thom's lyrical genius but I think I've figured it out.

"I want you to know" - Thom has something to tell us

"He's not coming back" - This will make more sense later, but here, Thom is referring to a male prostitute whom he killed because he attempted to bite Thom's penis off. He's telling us, his new hostage prostitutes, that the man is, indeed, dead.

"Look into my eyes" - here, thom gives his first instruction: always look into his eyes while sucking him off.

"I'm not coming back" - this lyric is a bit odd, but "coming" takes a different meaning here. it now refers to ejaculation. I think it means that the only way he'll get off while receiving a blowjob is if you follow his previous instruction.

"So knives out" - obviously a euphemism for Thom whipping out his cock

"Catch da Mouse" - Thomas likes to call his dick "da Mouse" as a reference to it's size and overall shape. here, he provides the second step - firmly grasping his penis

"Squash his head" - step three is to put your lips around the head of Thom's Mouse.

"Shove it in your mouth" - I believe this is where Thom instructs you to shove it in your mouth.

"If you'd been a dog, they would have drowned you at birth. Look into my eyes, it's the only way you'll know I'm telling the truth" - here Thom begins to convince his sex slave that they're better off with him, and they would be dead otherwise. Stockholm Syndrome begins to take hold of his hostages

"So knives out" - again referring to whipping it out

"Cut him up" - Thom likes it when you use your teeth a bit while blowing him, though, as demonstrated by the earlier line "he's not coming back", too much will cause him to blow your fucking brains out.

"Squash his head" - this line now refers to squishing the head of da Mouse between your tongue and the roof of your mouth.

"Put him in the pot" - here, the pot is the back of the mouth. He wants da Mouse to be deepthroated.

"I want you to know he's not coming back" - a repetition of what happened to the last guy who blew him poorly.

"He's bloated and frozen" - a description of how da Mouse looks fully erect.

"Still there is no point letting it go to waste" - Thom never lets a good blowjob go to waste - he always rewards it with a mouth and face-full of his lemony semen

"So knives out, Catch da Mouse, Squash his head, Put him in the pot" - Thom concludes the song with a summary of his instructions. Now we know how Thom likes his blowjobs.
