Based off Disney's character, Pumbaa is used to describe the "big" one in a group of girls who typically cockblocks guys from the prettier girls in the group. Pumbaas exist because they do not get any love and thus prevent every other girl in their group from getting love as well.
Man did you see the pumbaa swoop in and grab her girl away from me?

Man that pumbaa was real nasty, I think she even had tusks on her.

Get the Pumbaa mug.
A homosexual, tropical and overweight species of wild boar that thrives with its close sexual partner (Timone) in the movies "The Lion King" "The lion King II: Simba's Pride" And "The Lion King One and 1/2"
A Pumbaa has blood red coloring, long pointy tusks, and a short stumpy mane of black pubic hair, he can be seen obsessing over his lover Timone deep in the rainforests somewhere in Africa.
The Pumbaas' diet consists of insects, worms, and various dead animals- much of which it gathers with its tongue and tusks.

That male Pumbaa is obsessing over a male Meerkat!
That Meerkat must be a Timone!
Oh look! They're making gay love together!

To give birth to Pumbaa is to push out a huge log ... to have a shit ... It's big, brown and smelly just like Pumbaa from The Lion King ... think of Pumbaa being born.
