AISLE 4 is the proper interjection to use when a high level of awesomeness or accomplishment has been made.
This would be screamed when reaching the top of a mountain, discovering something amazing, or giving praise to a risky daring decision
"dude I climbed to the top of the water tower last night and got some amazing pictures"
"hahaha no way man thats soooo AISLE 4"
"Holy shit we found a new cave! AISLE 4!!!"
