If a guy texts you “heeey” instead of “hey”?

[Anonymous]

What does it mean when a guy texts you “heeey” instead of just “hey”?
And he also ads lots of vowels also to other words.
What does it mean? Is he happy to text to me or is just something guys do with everybody?

It means he's an idiot who can't spell.

It means he's high as hell.

It means he's not very good at spelling.
