Pa-Ching
Pa-Ching is when something shines so bright it makes your eyes hurt. It's like the sun decided to take a nap on your face.
'That neon sign? Pa-Ching. It's so bright I can't see straight.'
'The cake was glowing. Pa-Ching? More like Pa-Ching with a side of frosting.'
'He walked in wearing all the lights. Pa-Ching. I was blinded.'
