Euphemism for having sexual relations with an incredibly attractive woman, i.e. you're "taking her temperature" vaginally with your penis instead of a thermometer.
The gorgeous blonde paralegal with whom you work walks into your office, and your first thought is "I SO want to lick her pussy and take her temperature."

My wife looked a little under the weather, so I tried to take her temperature with my meat thermometer. She perked right up.
