What is ‘em?

Why "in" and "here" is used together? How are "What's going on in here" and "What's going on here" different?

This is a good question. In this context, both "what's going on in here" and "what's going on here" can be used to express the same general meaning. "In here" is often used to refer to a specific place, usually one that is enclosed in some way (like a room). Thus, we can interpret the speaker as meaning "what's going on in this room" with the "in here" meaning something like "in this room." Generally, you have a choice to use either, with "in here" meaning "in this specific, enclosed space," while "here" means "this location." Ex: A: Where are you? B: I'm here at work. (This location) Ex: There are so many mosquitoes in here! (This room/enclosed space) Sometimes, both can be used, like the example in this video. Ex: It's crowded in here. (Enclosed space) Ex: It's crowded here. (General place)

What does "kick some ass" mean?

Can you tell me about the Presidential election system in America? The electoral college is so confusing!

I can try! It definitely is confusing. The electoral college is a system that was designed back when the United States first began, and information traveled too slowly to inform all the citizens of the latest political news. It allowed states to vote for a representative who would then go to Washington D.C. to vote for the president on the state's behalf. Each state has a certain number of representatives based mostly on the population of the state. For example, California has 53 representatives since they have a higher population. Wyoming only has one representative because it's not as populated as California. In November, citizens place their vote for a representative who will then vote for the president on their behalf.

I suppose the exclamations are useful tools in conversation, and can you tell me some examples that can replace "I can't believe it"?

"I can't believe it" is an exclamation used when something is too amazing, surprising, or shocking to be true (although it is). You can also use the informal expression "there's no way" (very informal), "this/it can't be true" (very informal) or "is this (for) real" (very informal) in this situation, although their casual nature makes it a little awkward in this particular context. Ex: A: I won the lottery! B: Are you for real? Ex: A: I heard Stephanie got full marks on the university entrance exam. B: Wow, I can't believe it! C: There's no way.
