Imaginary Lat Syndrome is a common case of someone, typically a male, who believes they are rather muscular when in reality this isn't the case. Those with Imaginary Lat Syndrome can typically be seen walking uncomfortably while flaring their small lat muscles and tensing their arms in an attempt to look "jacked." In reality, it appears douchey and looks like a toothbrush has been shoved up their ass. Manlets are at high risk of falling victim due to overcompensation reasons.

The imaginary sensation of having huge latissimus dorsi muscles or "lats". ILS for short.

Men or women who look like they are carrying two wide suitcases one in each arm in a rush and are about to miss there flight.
