According to Urban Dictionary:

Powelled

To f*ck up in a way that results in a media frenzy. Whether it be figuratively or literally. Derived from Gary Powell, the Apple employee who lost the next-generation iPhone prototype.

“Gary powelled when he got drunk at a bar and lost the new iPhone prototype.”

Or, “Lucy powelled when she said that Labour’s pledges weren’t worth the stone they are carved on…”
