This is a stalactite. | This is a stalagmite. | Uh, this is a stalemate. |
A stalactite holds tight to the ceiling while a stalagmite just might reach up to the ceiling.
There were some spelunkers who were at a stalemate because when they saw a stalactite and a stalagmite formed together as one unit; they finally decided that what they had discovered was a stalacto-stalagmite.

See Jimmy, this is a stalactite, a word that comes from Modern Latin stalactites; but before that it came from Greek, stalaktos, meaning "dripping, dropping," or "to drip."
Now, this is a stalagmite, which also came from Greek stalagma, "a drop," or stalagmos, "dropping;" through New Latin stalagmites, "a drop" and both of them came from stalassein, stalak-, "to drip."
Finally, when a stalactite and a stalagmite join, we end up with a stalemate.
Just joking. It's really called a stalacto-stalagmite and it is pronounced [stuh LAK toh-stuh LAG might]. It is defined as a columnar deposit formed by the union of a stalactite with its complementary stalagmite composed of mineral-rich water; but, if it is easier for you to remember, it is also called a "column". Now you know all about these cave formations, don't you?
O pendant stalactite,
Deposit crystalline,
Insensate troglodyte
Shaped of accreted brine,
Aspire you still to pierce
That upright stalagmite
Who in a million years
Your love cannot requite?
And if indeed your drip
With ardor one day fill her,
And bring you lip to lip,
And make you two one pillar …
Still, how can you be sure,
O pendant stalactite,
If you are you, or her—
An upright stalagmite?
