This situation in which an individual finds themselves armless and also in desperate need of a lift somewhere. Rather than sticking out their thumb in hopes of getting a car to stop for them, they are left with no choice, due to lack of arms, to expose their rock hard dong out from their fly to simulate the same effect.
Man1: Oh shit I just remembered I'm gonna have to hitch hike to the Vietnam memorial service, but I lost my arms in the war!
Man2: No excuses! You still gotta dick ain't ya? Looks like it's the armless Hitch hiker for you...
When somebody tries to escape from a difficult or unconfortable situation by pretending he/she is not able to face it or doesn`t know how to do it.
C'mon! Frank was not sick that they we were carrying our furniture to our new office. He didn`t show up only because he is an armless John, that lazy ass!
