The act of non-consensual anal sex with a prior warning. In order for it to truly be considered a swedish blowjob the victim must be warned to stop an activity or they will be given a swedish blowjob. Typically a blowjob is an act of gratitude or admiration which makes the threat of a swedish blowjob appear less threatening to the would be victim, but is in actuality the most aggressive form of sexual penetration save only a skull rape.
"Stop being such a little bitch or I'm going to give you a swedish blowjob!"

"Come say that to my face and I'll give you a swedish blowjob!"

Or, in a slight variation, "I was doing so well and then I got a swedish blowjob".
