It's a term that belongs to Choi Soobin who is a member and the leader of the korean boy group Tomorrow X Together. Soobtonin is from Serotonin, the chemical that make you feel more focused, emotionally stable, happier and calmer. Just like Soobin ^^
Guys, when Soobin giggle, speaks in a warm voice, make chaotic dance and do his loveable things he gives me a huge amount of Soobtonin dose
