adj. Mmm...post-coital beefy goodness.
Real citation: "In short, I've been comfortable. So comfortable I've bugger all to write about. Even now I sit here post-beefgasm (that exquisite sensation felt after ingesting 400+ grams of marinated char-grilled scotch fillet), quaffing a glass of Mr. Riggs Shiraz and tapping away at the keyboard over my ever-growing paunch."

Made-up citation: "I haven't eaten beef in 15 years, so I don't know much about the post-beefgasm state. If it's anything like the happiness my dog finds in chewing on pig ears, I'll just stay ignorant, thank you."
