KMFAO!!! Could have been from any aircraft on the freq. When I was flying communter back in the 90's we had what we called the "Short Count"" freq 123.45. We all have handles and would get on there talk all kinds of shit. "How boutcha com'on" !!
Eventually a private airport somewhere in NC complained to the FAA about all the crap they were hearing on their CTAF freq. and the CP had to put out a memo to stop broadcasting on 123.45!!! kek'n
He was one of the worst offenders himself!!! We called him 9 to 5!! He had to stay current so his ass was out there with us a lot of times.
