An inordinate obsession with Olympic swimmer Ryan Lochte mainly due to his ridiculously hot body and face not necessarily his exceptional swimming ability. Symptoms include but are not limited to searching for him on twitter everyday, tweeting at him or about him frequently, making memes about him, looking up latest news stories about him, daydreaming about him, wanting to jump into your tv and tell him to "take you now", fantasizing about licking his abs, hating other girls or gay men that also think he's hot and so on.
Could also be simply referred to as "Lochte fever"
Delusional Lochte Fan: I have like 600 photos of my future husband Ryan Lochte on Instagram.
Confused non-Lochte Fan: Looks like you've got Ryan Lochte Fever.
