“Probing” (AKA cloacal probing) is when you insert a slender (important word here) lubricated rod into the snake’s cloaca (vent). It is best to use a suitable sized probe when probing. This is done by gently inserting the probe against the posterior wall of the cloaca and gently guiding it into the base of the tail, (from the vent towards the tip of the tail) and measuring how far it can be inserted. The probe can be inserted further into the base of the tail on a male then that of a female. The probe passes inside the inverted hemipenis of a male snake unlike stopping sooner when inserted into the female hemipenial homolog (a funnel shaped “pocket”). To determine the sex when probing you use your fingertip to mark the depth of the probe when inserted. Then the probe is removed and placed on top of the tail where you count how many subcaudal scales deep the probe went. With most species, the depth in which a probe can be inserted with females is usually1-2 subcaudal scales, while with males the number of subcaudal scales are greater, usually 8-16.
“Popping” consists of, with the snake belly up, applying pressure (I would call it rolling) on the tail with your thumb while moving towards the cloaca (vent). In doing do so, the inverted hemipenis will generally “pop” out. While both sexes have scent glands they are sometimes mistaken as a hemipenis. An experienced person can tell the difference while a novice may be misled. You will want to start applying pressure about an inch beyond the cloaca, too close and you may be hindering the hemipenis from popping out.
With both procedures, I believe it is best to observe it done by someone who is experienced and then I’d suggest practicing on a known male, then female (or vise versa) until you feel comfortable and get the feel for each sex.
