Sometimes called a slant and go, sluggo is a pass pattern where the receiver runs a slant and then breaks vertically up the field.
The route can be run with a quick slant or a standard slant. In practice the slant portion of the route tends to be short because once the defense has reacted to it the receiver wants to make his second cut to gain separation. The route is effective for getting a receiver into the seam and beating man coverage.
