I feel like that’s so much more common that it’s a different category of failure. The “out” part of Tapout is the outlane which is much less common, and worthy of it’s own term!
I call either variant a “crap-pass”
“TipTap” for a would-be Shatz or alley pass that changes to a tap pass at the last moment.
My “old sounds” memory circuit heard those and now suggests “El-Kabong” for a failed alley pass that hits the opposite flipper end hard and then center drains.
TapOut sounds great, but for just the side drain version. The too-weak version could be Tapathetic.
