Throw my crispy chicken wrap under the bus

To vomit uncontrollably. Similar in usage to "worshipping the porcelain god" or "tossing one's lunch".

That norovirus I contracted at the Tough Mudder race last weekend made me throw my crispy chicken wrap under the bus.

The morning after my 21st birthday, I threw AT LEAST 4 crispy chicken wraps under the bus.

Under the bus

Something to be kept secret; Kept in the closet

"Did you know those two are dating?"

"Yes, but they said to keep it under the bus."
