Sway
'Sway' is the adjective/adverb form of 'swag'. Just as swag is a pointless word that can be used in any freakin' situation for any freakin' purpose, sway can be used to describe anything in any way; though it is usually considered positive.
"Man, look at that hipster trying to act sway. I thought they gave up years ago..."

"Still more sway than yo' mama!"

"That was NOT a sway thing to say! *pimp slap*"
