Illegal, but in a chill way.
Parents: If you drive people you'll get pulled over and ruin our lives! You're not allowed to drive people until you've had your license for a year (in California)!
Me: Relax, it's not illegal. It's chillegal.

Thepiratebay.com and Frostwire are both very chillegal.

Word that is usually said when another person describes a bad situation he's in or something that happened to him or something that concerns him. The well-known word "chill" forms this word, implying that the person who says it is trying to tell the person in the bad situation to chill/stay calm, ensuring him that everything is fine. This word may sometimes be used the same way as "sheesh".
Him:Guys I just got an F on my maths exam.
