look up any word, like fleek:
 
1.
Phrase used to describe the act of writing useless software, and not excellent code as what some may believe, after partaking in the consumption of 'several' cold beverages.

Dervied from:
'Stella' coming from Stella Artois, a lager brewed in Belgium and after consuming a few can lead to an altered state of consciousness, and 'Code' as in what Software Developers create.

The act of writing "Stella Code" usually occurs on a Friday afternoon. I.e. after coming back from a "liquid lunch".
User: This software doesn't work anymore?!
Support: That's because it was hacked by John on Friday who is known for his Stella Code.
