O.M.L. Syndrom 

Old Man Love Syndrom
A syndrom common among younger females that makes them obsessed with older men. Not in any sexual manner but just as one would adore a cute puppy or small rabbit.

symtoms include (but are not limited to): raising of the voice to high pitched baby talk, self hugging of the body at first sight of an old man, confusion and loss of current thought patterns when shown a picture or real life visual of an old man.

Stacy - "awwhh, look at him! He's so cute!"

Ken - "..who the old man over there?"

Stacy - "yes! I just wanna hug him and squeeze him. abugabugabuga."

Ken - "I knew it! you have O.M.L. Syndrom!!"
