Like wonderbread only tan; a white person who is ridiculously tan because they spend too much time in a tanning salon "toasting" themselves.
I am meeting Wonder Toast at the bar later on tonight...after her tanning session.
Someone who is naturally pale and would normally be considered "wonder bread", but has tanned so much in the tanning salon that their skin has a permanent brown and leathery appearance.
His girlfriend is fake. She wears Lee Press on Nails, bleaches her hair, and tans so much, she has turned into wonder toast.
