To hate someone or
something with a passion, to the
point of feeling sick when it or they near...
To show invollentary physical signs(shuddering, cringing, face or body twitching, eyes-
rolling) of hate towards an Item or Person when it nears.
That person that makes you
cringe at first sight... you're mentally allergic to them.
That country music singer's voice that sickens you at first sound... You're mentally allergic to it.
That certain food that the sight/smell/taste of makes you wanna puke... you
may not be physically allergic to it, but you are mentally allergic to it!!!
