Max Mitchell sez: Tim is a guy I know. He was helping some guy with his website. The guy owes him £400, so Tim stopped helping him.
This is a cellphone message left by the guy where he starts ranting and raving. Swearing and telling Tim he's going to go crazy if Tim doesn't call.
A minor version of Winnebago man. Nice bit of swearing with a London accent.
