"Who went with you to the concert?"
"Oh, a couple of my friends, and there was this one Halstead guy that nobody knew, but he was pretty awesome."
"How awesome?"
"Think light yourself on fire and laugh."
"Whoa....That's pretty awesome."

In poker, playing a "Halstead" refers to playing a Jack Deuce. Often successful at taking the pot with this hand, there are few that like getting beaten by this combo.
I had a halstead and he went all in, I flopped a Jack and caught a deuce on the river giving me two pairs to his one!

When a doctor defies patient wishes, hospital policy, laws, or any combination there of to perform a procedure or provide medication they believe is beneficial. All the while maintaining an attitude that is or akin to self-righteousness.
Person 1: why did that doctor lose their license?
Person 2: they wouldn't stop Halsteading.
--------
Doctor: I need to do this to help this patient!
Nurse: doctor, you are halsteading. Please calm down.
