Testicular + peculiarities : cockup stuff males never admit as wrongdoing! And just go blame it on their male hormonal make-up... , y'know?

I liked that word so much, I searched my 'wordrobe' for more and here's what I found (you'll be gobshite-smacked!):
-MACHOs: males acting childish, hormonal and obnoxious!
-egotesticles: egotistical testicles! HAHA!
-testyria: testicular hysteria!
-testosterone-poisoning: an excuse whenever you miss up stuff so bad!
-MAS: male-answer syndrome, or 'manswer'... is the tendency for a male to come up fast with a random answer even if he has zip idea what's he talking about, fueled by testosterone!
Testicularities? Heh, you telling me? Blame it on the T!
