Get the cock-a-saurus-REXmug. When you're going down on a girl and she orgasms so hard that her arms go numb and she holds them like a T-rex.
Female- "OMG ! You are the Clit Commander! You gave me face so good I got T-rex arms!"
Male- "Yeah, that's a thing I do. I've been working out at the Y a lot lately!"

Get the T-Rex armsmug. 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.
