To sneak onto the TTC (Toronto Transit Commission) without paying. Originated from the song 'Baby Buluga' by Raffi as the extended jam (I know you've heard that one) contains a reference to stealing a ride.

"Baby Beluga in the deep blue see,
He snuck on to the TTC for free"
- Raffi (1980)

Recently the definition has been expanded to include stealing anything under $3.25 (the cash fare to ride the TTC).
Adam: Ugh. I don't have any change for the TTC. I guess I'll have Beluga Whaling it today. (Original meaning)

Adam: I don't have a pen. I guess I'll have to go Beluga Whale one from Stacy in accounting (new modified meaning)

Get the Beluga Whale mug.
Also the name for Ryan Joseph Young. These huge body’s only eat certain food and whether it’s good for them or not they will still eat it due to their huge stomach capacity. If the male creatures eat too much they can get this very rare condition called “man with tits”. Don’t get yourself fooled, if you see one of these you better call for help because it’s very very rare to see this.
“Holy fuck! I didn’t know beluga whales eat big macs!”

Kid- “look mom! that beluga whale has HUGE tits!”

Mom- “no son.. That’s just spydee”

The act of diving away from someone and mooning them on your way out above the water
I panced my sister's bikini under the water as a prank

Instead she yelled BELUGA WHALE and dove away with her bare bottom popping above the water
