It's hard to know, but some examples of phrases or slang terms might be: one sec - wait one second gotcha - I understand what you're saying no way! - it can't be possible no kidding - isn't that the truth (used sort of sarcastically) come on - either "hurry up" or used as a way to show you don't believe what someone is saying You could go on and on when making a list like this! Also different countries and demographic groups use different phrases/words. For example, a typical American teenager uses the word "awesome" for every and all situations. A middle-aged Canadian may say "pardon?" and seemingly most Australians will call people "mate." A young Brit may exclaim "crod!" which is unheard of in North America. So there you have it! I hope this was helpful.

Verb - "to be" I would imagine.
