When you have done something really bad which you hope no one ever finds out about, but you inexplicably and unintentionally hand the evidence to the police/the boss/you wife and suffer the consequences.
Doing a Glitter refers to Garry Glitter, aging UK glam rock star, who handed his PC into the repair shop as it had crashed, but he forgot it contained hundreds of pictures of child pR0n. They called the Cops. He was soon convicted as a sex offender and jailed.
Not to be confused with "Up the Glitter" which is what he was supposed to have asked the underaged girl in Vietnam, which was where he ended up after leaving the UK. Again he was convicted and jailed.
A metaphor for spending a lot of time making something that in the end is useless.
"You could spend months meticulously constructing a clipper ship piece by piece in a glass bottle. Or, you could do the Republican method and just roll a dildo in glitter."
