something shiny

A phrase used to explain a personal lapse in memory, coordination and/or good judgment by falsely attributing it to the phenomenon of being distracted by bright, pretty things (i.e. diamonds, fancy cars, jewelry, "bling", etc.), especially where the desire is to make light of it; often used in conjunction with a list of actions or other phrases like blah-blah-blah or yada yada yada; a take-off of the concept that blonds are distracted by "something shiny"
