Yetis look back on their tour

Just came across this article about the Yetis' tour earlier this year.

Fascinated by the line near the end when Lisa Coolidge says:

“We were billeted in Letchworth and got to meet the whole team there and learn some British slang. It was a great experience.”

Who put Lisa up? Anyone care to let us know what particular bits of slang they taught them (if it is printable)?
