Indiana Snowplow 

When you ejaculate on someone and use your cock and balls to push it around like a snowplow.

I got my cock all sloppy doing an Indiana Snowplow.

Indiana Snowplow 

A disturbing sexual method used in an orgy, where an ejaculation is directed onto another penis, and then inserted into someone else's orifice.

Anyone who does the Indiana Snowplow has got to be gay...
