Sorry reptilez but you cannot guess a bubblegum corn because its "pink"
All snows are VERY pink when they are young. All of them basically. You can guess you have a bubblegum corn if you know the parents look that way, or you just wait and let it grow up.
Bubblegum isn't a morph, its just a snow corn with some nice colors, like you said its just a word for a certain look basically. so its unpredictable with snows under 8 months I'd say unless you know what the parents look like.
Baby snow corn that hatched recently:

This baby is super pink, but will not be "bubblegum" as they all look this way when they are young and the parents don't look "bubblegum ish"
Good luck!
