That's because McAfee doesn't want those unfamiliar with football to think he solicits prostitutes.
One of several meanings for the word, according to the dictionary.cambridge.org, is the British slang definition that means a person who "uses the services of a prostitute."
"(A punter) utilizes a lot of pornos, basically like scum," McAfee said. "They're viewed as a scummy person. Somebody that is a weasel. Let's not get crazy, but it's a pretty good word."
So will McAfee tell people he's a fourth down kicker in London?
"If people don't know what a punter is in football they're not going to know what fourth down kicker is, either," he said. "I assume there's a lot of intelligent football fans in England. But if they think punter is a prostitution person and porn person when talking about football, I'm just going to have to stick with ball kicker. Strictly ball kicker. And I think I'll be able to say it with a straight face, a good handshake and I'll keep it moving."
