Some kilt wearer cheeks were flushed with embarassment
Some kilt wearer cheeks were flushed with righteous indignation
Some kilt wearer cheeks were flushed with excitement or a remembrance of times long past
Some kilt lifter cheeks were flushed with alcohol or later a modicum of shame.

Some kilted cheeks were flushed by exposure or a pinch

But they all lived happily ever after.
