Splurging, then never regaining your mojo. Such was the case when Willie Harris had 6 hits in a game for the Atlanta Braves, then hit .190 in 51 games after.
"Hey bro, I just pulled a Willie Harris."
"What bro? That sounds kinda homo."
"Nah man, I just jerked it before I knew mah girl was comin' over, then when she got here, I couldn't finish."
Pulling a William indicates that you have royally screwed up. Somehow, despite every possible odd, you managed to make the impossible and incomprehensible existent. Pulling a William also involves the "William Puller" to laugh maniacally after committing their act.
William Puller: *tries to build a house, but accidentally builds time machine operated by a rat with a lightsaber for a tail*
Barely squeaking by (or barely passing), or pulling it out of your ass.
In reference to the radio show, "The Bobby Bones Show" - when the cast was playing The Name Game, the cohost Lunchbox barely squeaked by naming "Free Willy" as a "Bill" or "William," thus causing controversy in the studio.
