Deconnia 

Deconnia is an uncommon girls name, most popular in Alberta, Canada. A true Berta legend which is synonymous with "mad lad". If you're looking for someone who is one sick puppy, look no further. Deconnia's tend to have a tenacity for "Wu-wu" shit. Have an upset stomach? Well Deconnia is sure to recommend some elderberry extract because she knows what's up. Staying up late and being independent goes hand in hand with being Deconnia. She's got ideas of what she wants and she's making moves on how to get there. She is friendly and sociable though first coming off as reserved. A truly selfless person, she struggles to say no and loves to include others in her plans. A pillar of the bioeconomy, Deconnia's feel most at home studying lignin and considering if carbohydrates have a crystalline structure. Deconnia's make great friends and are generally well liked by all.
