A person (usually called Andrew) that on the surface is relatively normal, but eventually shows the sass that is bubbling within. This is usually evident after 1 month of knowing them or observing them after half a pint of lager, whichever comes first.
Person 1: Hey, Andrew seems like a pretty cool dude!
Person 2: You’ve only known him a week, wait until we go to the pub on Monday!

*Monday*

Andrew: ...and that’s what your mum said!
Person 2: I told you he gets like this after half a pint.
Person 1: You’re right, he’s such a Sassdrew!!
