It really depends on what you consider a swear.
Things like "Feck" "Shit" "Shite" "Fuck" "Hell" "Drov" Are all pretty basic.
But if you are really mad and want to be creative be like.
"His light's shining ass hole" Or something, is where the big boy gasps and awe come from, depending on where you are of course.
Though I don't really have a list...the slang page and the page on the website is basically all there is, unless you want to be creative. Or I'm completely wrong.
