Causing your partner to laugh while releasing semen into their mouth.
Tell a joke while she's sucking your dick and you may get yourself a good cumchuckle.

When one has uncontrollable giggling or chuckling after having an orgasm. Similar to the giggles one gets after smoking good cannabis.
"Damn. What are you even giggling about? Do you have the Cum Chuckles or something?"
