how you respond when someone gives you a false compliment/says something out of politeness and you want to let them know you're onto them.

can be said either jokingly or seriously.

often followed by a) "I really mean it!" or b) a lengthier explanation comprised of dead air and bs.
a) girl 1: OMG you look so fabulous in that dress!
girl 2: aww, hon i know you're just saying that!
girl 1: no babe, i really mean it!

b) boy: i love you.
girl: puhleeze, you're just saying that.
boy: boo, i love you like the stars and the moon and the sun... (continued bullshit)
