i assume we are only talking about matches that are not just toying around with friends. cause everyone calls out stupid stuff in those matches.
calling MP or SP or BP in competitive matches is something that appears to be alot more common in the older generation. at least around here that is.
to be specific i dont think ive heard anyone under 40 doing it.
about out calls.. i guess im standard. i call out when they were close but just give the finger sign otherwise. serves i usually call "no" just because i dont want to start the whole long - out - fault - wide - whatever debate. no means no so that should be clear.
if a ball hits the fence or misses it and goes straight for the river instead i dont do anything. if anyone ever feels like that point should be theirs id probably just leave and get something to eat.
