First, I should confirm the translation. Is "di gangguin" the correct translation? "Di" is the passive form, so "diganggu-in" might be the process of being disturbed. So "Adek lagi tidur malah di gangguin" is "My younger sibling is sleeping, yet instead being disturbed." The person is probably upset or annoyed that their sibling is being disturbed when they should be resting.
Then there's "PoopHD11-19...". That could be an identifier, perhaps a video title or a hashtag referencing specific content. Maybe it's from a video where someone is disturbing their sibling. But without more context, it's hard to say. Adek lagi tidur malah di gangguin - PoopHD11-19...
Also, the use of "..." at the end might indicate that the post is incomplete, so maybe the user is seeking completion or more info. First, I should confirm the translation
