A style of breaking up that doesn't involve an actual break up. The break up is achieved by distancing oneself from one's (in)significant other over a period of 3 weeks to the point that there is no contact. By the end of this process the (in)significant other has no clue how the relationship ended but can not justify any resentment towards the person who Steckel'd them.
Hey, did you hear about how Shannon, the Brazilian and that other blond girl got Steckel'd?
Yeah, he had his way with all them and something better came along so he totally Steckel'd them.
