I don't know how to use 'partake' in a humourous way as stated in a dictionary. Could you help?
old-fashioned or humorous to eat or drink Would you care to partake of a little wine with us?
Your suggested sentence is fine. I would say that I have never heard of partake being particularly "humorous" - to me, it is simply old-fashioned. I guess I have probably said it when I'm trying to be "posh", so I suppose that could be classed as humorous.
"I have some really nice wine at home. Would you like to come to my place and partake?"
