Old term for making a mistake.
Ususally phrased "pulled a boner".
Why the word bone or boner means mistake, I have no idea:
Perhaps from accidentally hitting your funny bone, acting like a bonehead; or a grave robber pulling out a bone instead of jewels from a grave...just guessing!
Nowadays if you tell someone you "pulled a boner" they might think you are gay if you are a man or horny if you are a woman!
They really pulled a boner when they hired that bozo to run the steam roller: he flattened a BMW!
I thought that black guy on the phone was white--pulled a boner on that one!
Don't pull a boner this time you dope!
