this sexual act is performed by the male, and it is when he is on the side of a swimming pool or at the beach... so he inserts his feet into two girls vaginas and then proceeds to "plunge" into the water and uses the girls as flippers to propel himself through the water like a penguin.
i saw these two hot cunts laying out at the beach so i jammed my feet into their pussies and did the penguin plunge right into the ocean.

A contentious coffee brewing technique in which the plunger is pushed midway down the cafetiere several minutes into brewing. It is then pushed to the bottom within a few minutes to terminate the brewing process, leaving the coffee ready to be poured. The technique is said to produce strong coffee, reducing the bitterness generally attained from an extended brewing process.
"The coffee has been brewing for ages - you know it will be bitter soon"
"That's okay, I semi-plunged."
