Colombian Airhorn 

To make a loud audible sound of joy, satisfaction, or pleasure. A few examples of why one might let out a Colombian Airhorn are as follows:

1 winning the lottery
2 having explicit climax(es)
3 inhaling Colombian snowflakes

Despite contrary beliefs, the name does indeed derive from the little known facts that Colombia is known for it's snowflakes, while air horns are known for their loud audible noises.

I was giving rachel the dirty Isabella last night cuz I ran out of jerkzy to feed her, anyway dude when I finished bro, I let out the biggest colombian airhorn since my distant Peruvian second cousin, twice twice removed, visited me last winter.
