theres a main vein in your tongue, if you go to a good peircer, it wont be a problem, horizontal is just uncomfortable, you can never roll your tongue and it would just be stiff, longer healing, and you'd have to get PTF jewelry.
i hear so much talk back and forth about getting caught painting from workers not caring and never telling bulls due to the union and disliking the police,as long as engines and numbers are avoided. , to people getting a pile up of ridiculous charges for many years.
i personally havnt had encounters yet, and hope for it to remain that way.
