A slang term for pneumaturia, the passage of air or "gas" in the urine. A colovesical fistula, in which the bowel communicates with the bladder, may cause "dick farts" in addition to recurrent urinary tract infections. A man with pneumaturia may describe having "bubbles" when voiding, or may simply recall farting through his penis.
"Dick farts may be a sign of underlying Crohn's disease."
"Perhaps the strangest symptom I've seen is the dick fart."
