When a defensive lineman in football, makes an incredible and improbable sack on the quarterback.
Man, did you see Ray Lewis leapfrog that lineman and spin around the fullback to sack Joe Flacco. That was sackalicious!
A scrotum sack that glistens with moisture from semen or other moisture substance that makes it look juicy.
I just got out of the shower and look at my sackalicious nuts!
