"stall converters". Is it just me?

No different than somebody asking if it has a "cam in it". Obviously it has a cam because it's running. C'mon, we know what they mean. Do they have to say "does it have an aftermarket high stall in it"? Because some factory converters were "high stalls". How hard do you want to make it? Language is a form of communication, and if you know what they mean, it worked.
No..stall is a measurement not a part.
The best way to praise it, is that it has a "blankblank-hundred RPM converter"
As soon as someone drops the "stall converter" line on me, I automatically write them off as a ******* idiot, and nothing they say afterwards will carry any weight in our conversation.
