Result of when a man ejaculates into liquid, normally water such as a bathtub, pool, hot tub, cup, etc...

The act of planking while in the air with no support and hovering for a moment. The persons body must be as straight as possible, parallel to the surface below, with arms flush to their torso and give zero Fs to to forthcoming slam. The brief moment that all these attributes are true, and photographed is termed: St Louis Plank. Usually accomplished by jumping onto a bed (sometimes off another bed) and landing completely flat bodied and smush faced. Originating in St Louis in the early 2020s, this exercise can be performed either as a way to show total excitement or complete exhaustion and is most commonly performed by a person for an audience with a camera app at the ready. A variation, the St Louis Multi Plank, can be performed where at least 2 people attempt the SLP from opposing beds- ie that of a hotel room.
Friend1: Yo dawg, I just danced all night and finna passout.
