To receive a very sloppy, wet blow job. Typically involves spitting and excessive amounts of saliva.
Rachel slobber jobbed me last night. It was so wet and sloppy I nutted her throat in about two minutes.
When a blowjob is so voracious that the person administering the oral favor is salivating tremendously.
Heidi gave me the wettest slobber job on Tuesday night that I had to wash my shorts three times. So much saliva.
