look up any word, like smh:
 
1.
An IT jargon.

Meaning: "Gotcha" Bug - A bug is an error / a fault in the application whose severity may vary based on applications. A "Gotcha" situation in application development is when a programmer / developer oversees an issue / bug and it is spotted by someone else (peers / clients). Gbug situations are comparatively less severe: probably a teensy weensy thing overseen during application development.
Mr.John, there seems to be a gbug in this part of the application.

Everything looked good, except that one of our clients spotted a gbug in our application.
