๐ is the bikini emoji: a two-piece swimsuit. In a text it almost always means one of three things: beach, pool or summer plans ("beach tomorrow? ๐"), a new swimsuit or a holiday outfit, or, next to flirty emojis like ๐, ๐ฅ or ๐, a cheeky hint about looking good or showing some skin.
On its own it is a light, positive emoji. The tone comes from the emojis and words around it, so read the whole message, not just the ๐.
Short answer: there is no official or agreed meaning. ๐ฉ๐ฉ๐ฉ๐ฉ๐๐๐๐ (also written with a space, ๐ฉ๐ฉ๐ฉ๐ฉ ๐๐๐๐) is a string people paste and forward, and most people who search it simply received it and were confused. It is not a known code for anything explicit.
Read literally, ๐ฉ pile of poo is the usual stand-in for "crap" or for something silly, and ๐ means bikini or swimsuit. Repeating each emoji four times only adds emphasis. In practice the message is usually one of these:
If it comes from a friend, treat it as a joke. If it comes from a stranger or you are not sure, just ask what they meant or ignore it.
Paired with a couple emoji, ๐ turns romantic. ๐๐๐๐ ๐ or ๐ฉโโค๏ธโ๐โ๐จ ๐ usually means a couple's beach holiday, a honeymoon, or a flirty "can't wait to see you in a bikini".
๐ is the "kiss" emoji and ๐ฉโโค๏ธโ๐โ๐จ kiss: woman, man is its woman-and-man version, so together with ๐ the message is clearly flirty and best kept for a partner or someone you are dating.
From a girl: mostly literal. She is talking about a trip, a pool day or a swimsuit she bought, or she is showing excitement for summer. With ๐, ๐ or ๐ฅ and in a flirty chat, it can be a playful tease, but it is rarely more than that.
From a guy: usually a question about beach plans or a compliment on a holiday photo. Sent repeatedly to someone who has not flirted back, it can feel pushy, so keep the context in mind.
In a caption: under a photo, ๐ just labels a beach, pool or swimwear post.
The bikini emoji (U+1F459) was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015. It is supported on iPhone, Android, Windows and all major apps, so the person you text will see it.
Every platform draws it as a two-piece swimsuit. For a one-piece, use ๐ฉฑ one-piece swimsuit, which was added later.
