Interesting word!

I can't give a native perspective, but the dictionary gives me:

๑ เที่ยวป่า
๒ (ปาก) ดั้นด้นไปโดยไม่รู้ทิศทาง
๓ งุ่มง่าม ไม่คล่องแคล่ว, เช่น มัวแต่มะงุมมะงาหราเดี๋ยวก็ตกรถหรอก

And wiktionary (https://en.wiktionary.org/wiki/มะงุมมะงาหรา) gives us English definitions:

1. (literary, elegant, archaic) to tour a forest.
2. (slang) to ramble without a definite purpose: to wander, to roam, to rove, to stray, etc.
3. (slang) to move awkwardly; to be awkward.

Obviously it will depend on the context of the article/book, but assuming that 2. is appropriate in your case, I like "meander" for walking slowly and without purpose.
