It means when something is a tense moment, your ass tightens up. So a 'close call' is called 'puckering your asshole'

The sexual act in which one partner lays on the ground face first and proceeds to stretch their butt-cheeks apart revealing the anal cavity. Their counterpart must be a lactating woman; she squeezes her breasts into the anus, causing the nutritious milk to pour inside. The milk mixes with remaining fecal matter creating a delicious snack. She then kneels down and felches the milky shake out of the anus.
After hours of exhausting fornication, Jennifer decided she could go for a sphincter shake fresh from her lover's anus. Hopefully she doesn't wake the baby.

Not being able to take a shit in front of other people. Similar to being bladder shy, only with taking a shit.
I needed to shit so bad while we were on the beach, but due to the presence of other people on the beach, I became sphincter shy.

'is that my cum that just shot out of your ass and landed on my face'
'is that the reason my face has been so soft and clear lately'
'is this shit on my face or is it sphincter queef'
