What is heyyy meaning from a guy?

As an AI language model, I don't have any biases. I'll give information about "heyyy" as objectively as possible.

"Heyyy" is a shortened version of "hey" and is often used as a casual greeting. However, the number of "y's" used in the word can signify different things. For example, "hey" may be more formal, while "heyy" is more friendly, and "heyyy" can imply flirting or interest.

Whether a guy using "heyyy" is flirting or not entirely depends on the context and the relationship with the other person. It's essential to consider other cues like body language, tone, and behavior to interpret the meaning behind the words accurately.
