leap second

Leap second is a weird kind of second that is inserted at the end of a random day. During the leap second, the clock will read: **:59:60 (** is relative to where you are). The leap second is inserted to make sure that the clock is in sync with the Earth's rotation. The full list of leap seconds can be found by googling "leap second list".

The leap second is added, and now I can live 1 second longer!!! What will you do in the leap second?

When someone sends you a saved Snapchat (caption and all) over a different platform, making it obvious the original was meant for someone on Snapchat and you're getting their sloppy seconds.

Taylor must be talking to another girl, he sent me snappy seconds of his dog.
