When the dick goes in the wrong hole.
Sasha: OWWW MY ASS!!!
Johnny: Sorry, I have Dickslexia :/
A severe and crippling disorder found mostly in military males (U.S. Navy setting the record with 100% diagnosis) in which anything the discerning individual reads/writes/speaks just turns into "dick", "dicks", or a creative varient of. This disease has been the bane of many aspiring programmers coming out of the U.S. armed forces.
Richard was the company's lead programmer before he was diagnosed with Dickslexia, now all he talks or types is about male genitalia. At least he got hit by that "reincarnating in another world" truck while crossing the street, lucky guy.
A severe condition involving impairment of judgement and overall inability to understand the male sex
My dickslexia is kicking so hard this month I almost banged my carpenter.
