Any of a breed of large oversized women with bad hygene who call themselves "big boned". The breed tends to have a foul odor, wear out of date clothing, and dress in a proto-hippie manner. Typically feminist, will blame their lack of a relationship of weak minded men rather than their own fould odors or appearance. Most wildabeasts will deny being wildabeasts.

I'll never go in the ladies room after that wildabeast has been in there again! The smell was enough to make me retch!

When a male is nude and from the standing posture bends over to pick something up or stretch. The testicles are then wedged between the legs but protruding to the back side. Mimicking an image similar to a male wildebeest in Africa.
I was bent over preparing a bath for myself and my lady came in and caught a glimpse of the wildabeast!

You shave your pubes and hold them in your left hand. Then you jizz in her face then throw the pubes on her face! And then you make the chewbacka noise!
Why is there pubic hair on your face? Tom gave me the wildabeast last night.

something that you "shout out" when you want to exclaim something.
when you hit your head on something... like, say... getting out of your car... you then yell: "Wildabeast!!!"

or... you find out you got an "A" on a test you thought you did bad on... upon receiving that graded test back, you may then have the opportunity to yell: "Wildabeast!"

A stoner word for frozen pizza, prepared in an oven or microwave, then devoured with reckless abandon by a group of stoners who have the munchies. Rarely cut with a knife, the wildabeast is eaten by ripping apart chunks of dough, cheese, and sauce, and cramming as much as one can into one's mouth. The resulting scene is reminicent of a pack of hyenas devouring the carcass of an african wildabeast.
I am so blazed, I could really go for some wildabeast right now...

I must take credit for this one myself. A wildabeast is a girl that is so ugly, fat, hairy and nasty that you would expect to see her in Africa on a safari.
So are you going on safari? Cause that chick your hittin on is definitly a wildabeast
