A very reasonable request,cwh! I sit next to a former player at NCEL level, and subsequently a referee. He is noted for an impressively loud voice when berating opposition players and referees so SEPAR stands wholly unofficially for Stentorian Ex-Player And Referee.
In similar vein I have used the acronym UACSOTF - standing for Up And Coming Star Of The Future. Mr Hallam may well come close to that one, but a more testing game would be needed to earn it.
As for YLOMA - a Young Lady Of My Acquaintance.
I hope that clarifies things for you!
