2 Word Phrase Game

hey zogo, does it really always have to be the second word used in the new phrase? Based on the original post, I thought going from "pants (on) fire" to "hot pants" was a valid play, because it uses one word from the previous phrase, plus one new word. I have to admit though, all of your examples in the original post use the second word of the previous phrase.

Anyway, here we go:

coat rack

(even though I wanted to say "law suit" using the first word heeeheee)

edited to add: Aaargh, tenaj beat me to it! My new phrase is now

tail spin

Doctor No

way out

There again

up scale

back stroke

ego boast

Chair swing

Low cut

bait (and) switch

off white

board certified
