Example:
After a fart of great volume and/or smell, someone offers their hearty congratulence

Example:
Him: I am going on a sweet holiday yo!
Her:aww man congratulations I'm so happy for you but I am also a bit jealous! Congratulous!

Example:
You notice movement to your left. You turn your gaze to the object that startled you, and you notice someone looking at you. They approach you quietly, and you start to get a clearer picture of their face. It is glistening and glowing a bright white, like that of an angle coming down from the heavens. His striking blue eyes pierce your vulnerable soul, yet making you feel safe and concealed. His beautiful, perfect facial hair resembles that of a viking king. He hovers towards you, as if he were without legs. His beauty temporarily blinds you and sends shivers of pleasure across your body. 10/10, would smash, you subtly think to yourself. The masculine, effortlessly gorgeous man, clad in a stunning Simone Says jumper (that I really want please can I have it) approaches your inferior, mortal being. His soft, full lips gently touches your ear. You can barely stand. Your legs start to buckle at the heels. This is it. If this beautiful man does anything else, you will surely melt. But you know it's coming. And you can't wait. He inhales gently. 'Congratulations.'
-JK Rowling
