29 is akin to, in the words of most, "Humping a Humpback whale"

The 2 from sideways looks like a whale's hump and tail, hence the whale part, and the 9 is you. 29 resembles you humping a whale. It is a strange new thing that is catching on rapidly.
"I got number 29." Grant said.

"Oh silly," I said, "Don't you know that means? It means you humped a humpback whale."
