Slippy Wrassle
The act of covering one's bathroom or kitchen in a heady combination of olive oil, baby oil, and dish soap and then proceeding to duel a partner (usually a romantic partner) to physical combat on said slickened floor, usually to settle a disagreement or promote healthy communication.
Will challenged his husband Jax to a slippy wrassle to determine who would have to be the "mom" in their relationship.
