An exaggerated, informal version of “delusional”: unrealistically hopeful, imagining a connection, or choosing confidence over the available evidence.
When it fits: Use it about your own obviously exaggerated hope or in a group where the teasing is welcome. Acknowledge the gap between wish and evidence.
When to avoid: Do not use it to diagnose someone or brush aside a genuine concern. Calling someone delulu can shut down a conversation rather than explain your disagreement.
“The band liked one of my posts, so naturally we are best friends now. Delulu.”
In plain English: I know I am imagining far too much from a small interaction.

“Really,” “openly,” or “without trying to play it down.” It turns an opinion or feeling into a more direct declaration.
When it fits: Use it to express a strong casual preference or make clear you are no longer understating a reaction. The phrase sounds natural in chats rather than formal reports.
When to avoid: Do not substitute it for specific reasons in a review or assume a high-key lighting discussion is slang. Technical and conversational meanings are separate.
“I highkey think the second album is better.”
In plain English: I strongly and openly prefer the second album.
