What is prolly?

"Prolly" is an informal or colloquial contraction of the word "probably." It is commonly used in casual conversations, text messages, and online communications to convey a sense of likelihood or possibility in a more relaxed or abbreviated way. This kind of contraction is typical in settings where brevity and informality are preferred, such as social media posts or chat environments. It's important to note that while "prolly" is widely understood in such contexts, it is not considered standard English and may not be appropriate for formal writing or communication.
