When you really really want to emphasize that no one cares about something. Not only does it feel satisfying to say, it's a quick and easy way to shut someone down when they say something stupid or trivial.
Adil Benrlitom aka ScreaM started working with Finalmouse to create his own mouse called "ScreaM One." They made an ad for that mouse which was featured in the big CS:GO Major MLG Columbus. When Adil said the line "They talk about my one taps", it quickly became a huge meme in the CS:GO Community.

To "land one on the beach", or "landed one on the beach" is to take a shit that is so big that at least half of its unbroken length sticks up out of the water of the toilet bowl and clings to the porcelain like a beached whale taking its last breath.
Dude, you've got to see this. I just "landed one on the beach", It was such a big shit it brushed my nuts when it finally brokeloose and fell over. I love it when I "land one on the beach" I never flush those, so the next guy can see how insignificant his shit capacity is!
