"Wow, that shirt is totally lute!" (in this case it can be seen as either)
person 1, "I just
aced my bio
midterm!"
person 2, "
Nice dude, tottally lute!"
(here it is used as a compliment)
Person 1, "Your a loser!"
person 2, "oh yeah, well your tottally unlute!"
(here it is a slam)
these are bad examples, but i think you get the general idea.
