A dust farting old man who swindles people out of their hard earned money by letting them bet on Sunday football games when they are drunk at the topless bar on Saturday night. The Swede uses his gains to pay for his new Honda Accord, vet bills for his dogs, child support for all of his bastard children that he fathered while at Woodstock back in 1969.
Man, I lost $100 betting on the Swindling Swede's football games. I think we need to go jack his Honda Accord for giving out such bad advise on the games.
The act of continuing to date a girl you want to break up with while you start dating a new girl. It usually occurs because you either don't't know how to break up with your girlfriend, or because you want insurance in case the new girlfriend doesn't work out. The period of overlap is like the way shingles overlap on a roof.
John's was shingling with Alice until he finds a way to break up with Mary.
