A term that a kid came up with to rename the term of "manual shift" or "Slapstick" because he forgot what the S really stands for on a shifter, when I'm reality the car must be built default sport to be a sports car.
Kid: Oh crap, I forgot what the S means on my shifter, I'll call it sportmode because it makes me feel like I'm going faster.
Sport Mode refers to when your Johnson looks like a toddler’s after physical activity, hot or cold weather or in the shower. The bloodflow goes to different parts of the body leaving you looking like a flat balloon.
Dammit, my girl saw me in sportmode for the first time, now she keeps calling me earthworm Jim.
When your dick is all shrivelled up to retain heat/stay out of the way during athletics. Typically paired with a tightened ballsack for the same reason.
