(ง * ॑˘ ॑* )ว

The ˘ in the middle is the character Unicode calls BREVE, and under compatibility normalization (NFKD) it splits into a plain space followed by COMBINING BREVE, the mark found in letters such as ă. Counting code points, the face has thirteen, and that ˘ is the seventh, with six on each side; a ॑ comes right before it, and after one space comes the second ॑. The Thai consonants ง and ว carry the Unicode names NGO NGU and WO WAEN, which follow the Thai habit of naming each consonant together with a word: ngu means snake, and waen means ring. On X, someone put this face after すごい！ (amazing!), ありがとうすぎる、、！！ (roughly, so thankful it's too much) and はぴはぴ, so it suits a thank-you that keeps spilling over.
