canalingus
When a dog licks your butt.
I was awakened the other morning by my dog performing canalingus on me. I was thrilled for a third of a second until I woke up, realized whose tongue it was, and kicked him out of bed.
Canalingus
The act of licking or rubbing ones tongue on the rim of a can. Similar to cunnilingus and analingus.
"Just chug that beer already. Stop giving it Canalingus and drink it."
