Cancer Emoji ♋

What ♋ means

♋ Meaning: A pair of loops with an extended tail on one end placed circularly parallel to each other. The ♋ Cancer emoji is an indication of the fourth zodiac sign. It would have direct references to all aspects of this zodiac; animal, planet, numbers, colors, etc.

How and when to use it

Since a crab fits in as the zodiac animal or rather the "marine creature" for cancer, you could use ♋ while referring to this sea animal or the element of water as a whole, from a 'spiritual' or zodiacal perspective.
From an explicit view, ♋ is often read as a '6' and a '9'. Hence, this emoji could have sexual (number 3) references too. This also means it could also symbolize intimacy, sexual union, and other related themes.
Also, if you look closely, ♋ looks like two lost souls swimming in a fishbowl. So, while texting someone wishing they were here, use ♋.
In general, using ♋ in any context would suggest that you're talking about astrology or horoscopes (and about Cancer, in specific). For example, "Well. Let's see what unfolds for people like us ♋".
