LGTM
Looks Good To Me
ELI5 — The Vibe Check
LGTM is the two-word code review approval that can mean anything from 'I carefully reviewed every line and this is perfect' to 'I glanced at the title and I trust you.' It's the developer equivalent of a thumbs up. When you see it on your PR, you feel a little rush of serotonin. When you type it, you may or may not have actually read the code.
Real Talk
LGTM is a common code review abbreviation indicating the reviewer approves the changes. In many CI/CD workflows, receiving one or more LGTM approvals from designated reviewers is a prerequisite for merging pull requests. The depth of review behind an LGTM varies widely by team culture and reviewer diligence.
When You'll Hear This
"Just got LGTM from the tech lead — merging now." / "Can someone LGTM this so I can deploy before lunch?"

A code review is when another developer reads your code before it gets merged, looking for bugs, bad practices, or anything confusing.
Merge
Merge is like combining two parallel universes back into one. You take the changes from your branch and smoosh them into another branch.
Pull Request (PR)
A pull request is like raising your hand in class and saying 'Hey, I made some changes — can someone check my work before we make it official?
Ship It
Ship it is the developer battle cry. It means 'this is good enough, let's deploy it.
