30/30-150

A type of Rifle round (.30-30). The 150 is the grain. Not sure what that guy is talking about with the whole rape thing, couldn't find anything about it.

Also, the name of the first track of Stone Sour's album "Come What(ever) May."

My Remington fires a 30/30-150.

Stone Sour's new song 30/30-150 is awesome.

30 30 Challenge

One 30 pack of beer, one crave case of white castles, one night. The first person, or team, to finish all of their burgers and beer is declared the victor.

After doing the 30 30 Challenge, the group of friends smelled like shit for weeks.

30 for 30

When Stephen Curry, the most well renown #30 in the current NBA and possibly it's entire history, achieves 30 or more points in a basketball game. This is a feat that he has achieved 213 times throughout his illustrious career, even averaging 30+ PPG for 2 of his seasons in the NBA.

And with that 3, it's 30 for 30!
