Given the context, I'll take a educated guess that "Ometv" could be a typo or variation of "Omegle TV" or simply "Ometv," which might refer to a video chat or streaming platform, and "abg sange emng mantap" could be a phrase in Indonesian. "ABG" is an Indonesian slang term that stands for "Anak Baru Gokil," which roughly translates to "Newbie" or "New Guy," but in some contexts, it can have different meanings. "Sange" could imply "excited" or could be used in a different context altogether. "Emng" seems to be a typo or variation of "Emang," which means "indeed" or "yes." "Mantap" is an Indonesian slang term that means "awesome" or "cool."
