The bull frog, similar to the the angry dragon is when a man is having intense oral sex with his girlfriend, she is in squatting position and slowly thrusts while she is going down on the penis. This will create a fire in her eyes, and in some cases disapproval. None the less, after continuing, give her a nice, firm, flick to the middle of her neck, or to use agression, a karate chop (excellent stress reliever) to the throat. The end result is a "whoap" kind of noise, similar to that of a bullfrog. She will angrily hop away like a bullfrog. Extra points if you catch it on audio.
Dude, last night was hilarious. Karen was pretty pissed when I gave her The bullfrog, but it was totally worth it.

The bullfrog is when you have someone put their mouth on your anus. You then fart into their mouth and the result causes their cheeks to flare out with your gas.

A quintessential act of Australian alcoholism, whereby the subject wraps their lips around the entirety of the glass’s rim and blows out to create a natural form of suction and conceal the contents.

Next, the subject whips back their head back allowing the alcohol to rapidly enter the oesophagus and swallow accordingly.

A fail proof method of gaining respect amounts peers and causing audience unexpected urination.

Not to be confused with any weird sexual positions.
