When a lady forgets to wear
knickers and proceeds
to flash her (gash) to all and sundry.
Named after singer Britney Spears who forgot
to put on her panties providing waiting paparazzi
an eyefull of her (lady garden).
"I'm not going to wear panties
tonight, I'm doing a britney"
that woman is doing a britney, I've just caught sight of her (snatch)"
