Australian Handshake

When a man and woman contract their pelvic floor muscles during penis-in-vagina intercourse, causing the vagina to tighten and the penis to harden at the same time, thereby squeezing down on each other as if to perform a handshake. Called “Australian” because it occurs “down under”—beneath the belt.
