When a developer enters lgtm mode, they stop critically reviewing code and start rubber-stamping everything with a thumbs-up.
When a developer enters lgtm mode, they stop critically reviewing code and start rubber-stamping everything with a thumbs-up. Maybe it's a Friday afternoon, maybe the PR queue is 40 deep, or maybe they just don't have the bandwidth to care — whatever the reason, every diff looks fine and every merge request gets waved through. It's the coding equivalent of nodding along without listening, and it's how bugs quietly sneak into production.

An lgtm fail is what happens when someone approves a pull request without actually reading it and the code later breaks production. The phrase captures both the action — the lazy rubber-stamp — and the consequence: a bug, an outage, or a security hole that traces back directly to a drive-by approval. It's the ultimate dev accountability moment, immortalized in post-mortems and passive-aggressive Slack threads alike.
"Looks Good To Me." Shorthand approval on a pull request or code review, signaling the reviewer has no blocking concerns. Can be left solo or stacked with emojis — "LGTM 🚀" for ship-it energy.
A sus lgtm is an approval that raises more questions than it answers — when someone says 'looks good to me' on code that clearly hasn't been properly reviewed, or gives the green light a suspicious amount faster than anyone should. The sus qualifier signals that the review itself smells off: maybe they're covering for bad work, maybe they didn't look at all, maybe they merged their own PR. Something is definitely not right here.

LGTM energy describes the vibe of someone who approves everything without pushback — at code review, in meetings, or in life. It's not exactly a compliment. The person radiating lgtm energy isn't engaged, they're just agreeable on autopilot, nodding at every proposal and signing off on every idea because friction requires effort they're not willing to spend. In tech culture especially, it signals low standards or someone who checked out long ago.
