Definition: The word you're looking for is "pantake," which means to have a good time and enjoy oneself in some non-essentials.

Pantake is slang for the phrase "funny pants" from Shakespeare's play "2 Samuel 8:2." In this quote, the character King Saul jokes with his friends that they should wear funny pants to lighten up their mood, as it makes them look more comfortable and happy. This expression often has a playful and exaggerated tone, but can also be unsettling or inappropriate if used inappropriately. For example, "I just got a new pair of pants! Funny pants!" (This would likely offend someone with a serious interest in fashion and not appropriate for an intimate social setting).
