Breasts aren't "boobs" or "titties" but rather "tiddies" or "titays"

"Titties" is a stupid word. It's so stupid and gross that some millennials are replacing it with even more ridiculous words like "tiddies" or "titays." Brilliantly funny MEL Magazine editor Alana Hope Levinson explores how "The Extremely Online are destroying language"-"one tiddy (or tity) at a time." From MEL:

I first started thinking about this when columnist merritt k wrote about the state of fake boobs and tried to get away with "tity""-"with one "t""-"throughout the entire draft. I thought it was a typo, but I was astounded to learn that merritt is on a one-woman crusade to make "tity" both the singular and plural.

Still, I thought merritt was a lone tity weirdo until I encountered "tiddies" in writer and designer Robyn Kanner's draft on trolling Instagram's nudity policy. "Tiddies""-"apparently also the choice spelling of my bible, Jezebel"-"first appeared when Kanner was describing a scene in Garden State where Method Man asks Zach Braff, Peter Sarsgaard and Natalie Portman if they "saw some titties" at a strip club. In this case, Kanner was using the double d (lol) as a pronunciation spelling common in slang cause she thinks it "has more swagger." "Titties with a 't' is nice, but it just sounds like college boys talking about boobs," she says. "Tiddies is 'we are older, but we are recognizing we are making a joke about boobs.'" Because "titties" is so ridiculous, making it even more so somehow neutralizes the effect with comedy"-"or at least gives you some ironic distance.
