"You've got talent and elegance"

Today, I was assistant referee for two games. The first game was a U14 wich went very smooth with nothing to talk about.
The second one (U16), I was working with the referee's boss. The first half went very well until a second before half time. I flaged for a throw in and the player of wich the throw in went against, looked at me and said: "How can it be for them, he touched it. (3 seconds pause.) You fucking pine." First of all, I don't have the slightest clue on earth of what is a pine, so couldn't bring it down to OFFINABUS (Offensive, insulting, abusive) language. The word fucking should have helped me guess that it was abusive, but I didn't take any action, just gave him the dirtiest look he might ever get. At half-time I was talking with the ref and he complimented me on my flag-handeling, aswell as our visual communication. He told me I had alot of talent and was elegant when signalling. The second half was a bit more difficult than the first as the play became a bit rougher and the tackles were flying in. The ref gave two yellows and did well to keep that count low. The first booking was for a foul wich he played advantage and booked the player a good 3 minutes after the original offence. The second for dissent.
Overall a good day for me and was happy to be able to find some time to referee. Hope I can build on this performance and become better and better.
