I live in Huyton (moved here in '88), all my scouse mates support either lfc or efc, it seems to be a support your local team thing as guys from nearby St Helens or Wigan tend to support their local rugby league teams. lfc have many supporters from outside the city, and efc have a strong base in North Wales. It's great fun to wind up both sets of supporters, more and more they resort to 'history'. Bluenoses are often more touchy, and easier to wind up.
One of the bluenoses refused to pay up on a bet. So when efc played Chelski in the cup final, he went to wembley and I called around to his house and decked it out with lfc memorabilia (my son supported them to my shame) and took some photos on my mobile. Then into Liverpool city centre to watch the game in a pub with some kopite mates and cheer on Chelski.
They loved the pics and even my bluenose mates at Wembley did when I sent them and they realised it was the tight git's house that had the make-over. He got home about 4 am, pissed, bad-tempered as efc had lost, Then had to take down all the kopite banners and pictures straight away, waking up the neighbours as he cursed doing it. When he finished and went in the house, he found I'd posted all odd socks through his letter box. efc were planning to move their ground to Kirkby, where even scousers used to joke you couldn't leave a pair of socks on the clothesline overnight without them being stolen. lfc fans would throw socks on the efc pitch at derby games.
He never paid up on that bet but I had my money's worth of fun at his expense.
