Defined by dictionary.com the word does not imply sexual exhaustion.
"I was on this one flight right, I'm flying, I'm trying to sleep on the plane, I'm fucking "knackered"; very tired right, and I feel this tapping on my head. I look up and there's this little kid - LOOSE!, On the fucking plane! Just loose! It's his playground in the sky. And he has decided that his job is to repetitively tap me on the top of the head.

And I look over at the mom and she's just smilin', and the guy next to her says "Aw, they're so cute when they're that little," and the mom's just smilin'.

Isn't that amazing, letting your kid run loose on a fucking plane... And then the kid runs over to the emergency exit and he starts flipping that handle next to the door. And the guy next to the mom starts to get up,
and I go, "Wait a minute... we're about to learn an important lesson right here."

Kwoooshh.

Why you're right: the smaller he gets, the cuter he is!
