I like your shoelaces
A phrase used by Tumblr people to catch other Tumblr people in real life. If you're cool, say, 'Thanks, I stole them from the president!' If you're not, say, 'I took them from a unicorn.'
@ben: I like your shoelaces
@ben: Thanks, I stole them from the president
@ben: I took them from a unicorn, you're a weirdo.
