The sexual act in which the male partner defecates in large quantities while holding onto his spouse. This is generally precluded by pulling a Chewbacca mask out from under the pillow, donning it and yelling like the titular Wookie.
"Have you tried the Filthy Chewbacca yet?"

"Aw man! Last night I treated my girl to a romantic dinner, took laxatives and had beautiful sex with her. After she fell asleep in my arms, I put on my Wookie mask, pulled her in tight, flooded the bed with shit and yelled like Chewbacca!"

Male: "*Chewbacca Yell*"
Girl: "NO! WHAT ARE YOU DOING? LET GO OF ME".
