If I had to choose one, it would be this
"I'll strangle you to death, then I choke you again
Then break your fuckin' legs till your bones poke through your skin"
That's just some ill-caveman shit. It's amazing.
Honorable mentions:
"I'm buzzin', Dirty Dozen, naughty rotten rhymer
Cursin' at you players worse than Marty Schottenheimer" <-- Multi's are amazing.
And last but not least, this line always stood out for me when I was a kid, until now I love it.
"Slut, you think I won't choke no whore
'til the vocal cords don't work in her throat no more?!"

And this, well, gotta love it for the meaning.
"That's why we- seize the moment, try to freeze it and own it, squeeze it and
hold it
Cause we consider these minutes golden"
Last but not least
"They make it all up, there's no such thing
Like a female with good looks, who cooks and cleans!"
"This dude doing this interview wants me to spin a few,
Lyrics while I tie my tennis shoes in the nude
A romantic interlude in a livin’ room,
In an inner tube with a dude with a bit of lube
Fuck that I’m sniffin’ glue, sippin' gin & juice,
And a little bit of paint thinner with my dinner too,
You better pay me for my bars like your rent is due,
Now hurry up and finish dude before I finish you."
