Mitch, we have first hand butthole experience in my Sunday Morning cycling group, a casual group of riders from mid-30's to about 75 years old who like to turn 25 - 35 miles early in the morning.
Every once in a while this guy shows up with (I kid you not) a $22,000 Trek custom-built track bicycle (that's the $$ is no object part). It's a very pretty bike with bells and whistles I can only dream about. What ever isn't carbon fibre is made from Titanium and everything on the bike is aero-conscious and designed with a wind tunnel - except for his legs...
Once we get rolling and because someone on a previous ride told him I have a '57 Porsche Spedster, all the guy can talk about is his Porsche GT-3 and his Wife's Panamera. When we hit the hills (and a couple of times we've done some soul-wrenchingly steep New England hills just because of him) he takes off like a jack rabbit at the bottom, only to run out of gas half-way up and all of us guys 30 years older just keep chugging along at our own pace and have to wait for him at the top to come gasping up.
He's not a butthole because of his bicycle or his cars.
He's just a plain butthole.
