Means 'seriously' or 'really'. Often used as an interjection or adverb. Can be combined with で (マジで).
Slang for 'hilarious' or 'that's funny'. Literally means 'to receive', but in slang it means something is laugh-worthy.

Many English colloquial expressions do not have direct Japanese equivalents. Trying to translate them word-for-word often results in unnatural Japanese. Instead, learn the natural Japanese expressions that convey the same intent in casual situations.
Colloquial Japanese varies greatly by region, age group, and social context. What is natural among close friends may be rude in a workplace. Pay attention to the relationship and setting before using casual forms.
