I like the example sentence for 'Thistle', I dislike it (a lot) for 'Thistle-Chaser', but 'Sly' is the reason I'm posting here instead of just leaving it as a comment in mctabby's LJ:
v. to slap a club.
"I can't believe Reggie tried to thistle!"
n. mid-nineties term for lipstick.
"All your thistle-chaser are belong to us, dude."
"Check out my sly tattoo!"
First person to make a comment on Sly's gets hit. :)
