Brief s'plaination: the latest stems for the handlebars are of the "threadless" style.
I have my stem in the up position so that it rises making it comfortable to my liking (positioned like the top red line).
Many times riders on the forum will see a picture of a bike like mine with the stem in this position. When they do, they say "flip it" meaning the stem so that it will be in the position and angle of the lower red line. That would be the race position, more aerodynamic and all that stuff.
The stem refers to the handlebar stem (marked with a thin green line)
