I don't recall exactly what our beef was, but it got particularly bad when he unilaterally invited his f*cking 12-year old nephew to an Awimb 5-a-side match that I'd organised.
Anyway, we met at the pitches and immediately started piling into each other. Clawet everywhere.
Only joking, we exchanged awkard bantz and then played a perfectly amicable game of highly mediocre football together.
