The insertion of a 10" bore syringe filled with a variety (or one) drug(s) into the urethra ( the syringe starts out small for easy insertion then expands once inside the urethra)
Lucas: Hey man, this one chick last night was so kinky! She tied me up in ropes then fucked me in the ass with a strapon

Braydon: Oh yeah? This chick I was with gave me a Roman growth-spurt. My penis will never be the same!
Lucas: Ripperoni Braydon's penis

When your child is physically, mentally or emotionally growing and temporarily regresses. Some forms of regression might be tantrum throwing, babbling nonsensical words, eating/sleeping a lot, and driving you and your childcare providers crazy. Similar to premenstrual syndrome, GSS comes in cycles and can be before, during or after a growth spurt...causing great confusion to you, and making you question everything about your own coping skills.

GSS remedies are bubbles, puppies, unicorns, sleeping and eating. Key identifiers are: You no longer know your child. You find yourself clawing at the walls. Your child has bigger chipmunk cheeks, is eating a lot and/or wants to go to sleep. Positive attributes: Your child is growing & learning.... and it is only temporary. :-)
Tyler is going through a major growth spurt syndrome (GSS). Tyler just bit the neighbor's child and is crying babbling words, I am hoping it is his growth spurt syndrome and not an ongoing thing. I don't even know who my child is when they have growth spurt syndrome GSS. Patience is watching my child going through GSS.
