An erection of such magnitude that it stretches out all the skin in your body, leaving even the skin on your face so drawn and tight that all you can do is utter "help me," which, because of the taut facial skin, sounds like "reltney."

Also spelled as "rheltney": a hard-on so intense that you can't breathe or blink your eyes. Paralysis can only be alleviated by sexual contact. In derivative Disney culture, Sleeping Beauty, (man with reltney), is awakened (un-paralyzed) by a beautiful prince (woman) by a kiss to her lips
(penis).

An erection that is so massive that you may only experience one in your life since two would cause death.

A hardon so intense that the wrinkles on your forehead disappear and your toes curl up.

An instantaneous hard-on of such speed & intense rigidity that it snaps your head back on your neck.

A boner so hard that a cat can't scratch it.
