The phrase aca con los nety en el ts is Spanish slang for being here with a specific friend group inside TS, short for TeamSpeak, the voice chat app long used by gaming groups. Clips like this spread as short soundboard and WhatsApp audios because the joke depends on familiarity, a named group and a familiar place to hang out. Without a confirmed public source or creator, its popularity comes from reuse among friends who treat the line as a greeting, resending it whenever someone logs on or enters the channel.
