What does vgl mean in texting?

I'm curious to know, what does the abbreviation "vgl" stand for when used in texting? I've seen it used in a few messages recently and I'm not quite sure what it means. Could it be related to some sort of slang or an inside joke among friends? Or is it a widely recognized acronym that I'm simply not aware of? I'd appreciate it if you could shed some light on this for me.
