The affliction suffered by someone who had an excessive workout the previous day, focusing on the arm muscles, and are now suffering extreme pains, leaving them to tuck in their arms all day to stay comfortable.
Too muchgym yesterday left me with a major case of T-rex syndrome
Happens when a person running (note: not a runner) runs with their arms tucked into their armpits and forgets to swing them in stride. Their arms look tiny and they look like a big goofy T-Rex.
Wow, that poor guy clomped by with t-rex syndrome. I could hear him from the other side of the street.
