farm harder

The act of sneaking into a local farm yard and inserting your penis into one of the animals. Preferably a pig or horse. Once you are about to ejactualte one must shout “farm harder”

What did you get up to last night mate?

Snuck into the local farmers field for a game of farm harder. What a great looking horse.
