Stephen Colbert I'd Like to Fuck.

When the opening credits play for The Colbert Report's new season, he grabs the American flag and jumps down amongst many Amurcan words. One of the first and only easily readable ones is SCILF.

silflay 

From Richard Adam's book Watership Down - it's a word that's part of the rabbit language Lapine - it means to go above ground to eat.

I didn't silflay with the rest of the warren this morning - I'll go tonight.
