The sexual act of placing your partner (preferably chinese, japanese, cambodian, etc.) at the end of a "slip-and-slide" ; however, the water is replaced with soy sauce. At this point the male slides down the filthy slip-and-slide on his knees trying to insert his penis into the on waiting partner in doggy style. A real expert of the Lowell Connector understands there is more then one ramp on the connector. So either the vagina or anus is an acceptable point of entry.
Guy: Dude, you smell like shit what happened?
Friend: I know bro, last night me and Sun-Li did the Lowell Connector and i cant get the soy sauce smell out of the burns on my knees.
