I took this bird home the other night and when she took her bra off I was confronted by the most tremendously long set of stalagtits that I have ever seen.I was gripped.

Candarian stalagmite 

A turd dilivered from a human anoose inside of a cave that stands proud and erect rising from the cave floor pointing towards the ceiling. The Candarian stalagmite has a remarkable resemblance to a regular stelagmite.

It is good fun to drop a Candarian stalagmite and have it discovered and examined by unsuspecting spelunkers.

Horizontal stalactite 

Is the build up of semen on the rear divider of a desk. Overtime the dried semen forms a stalactite on the horizontal plane.

What is that under your desk Jimmy?
Oh that's just my horizontal stalactite Mum.

stalagmite

The act of ruining a joke, or being not funny. (To replace the awkward silence after someone kills a joke).

After Pat tried to add on to a joke with a dumb comment, instead leaving an awkward silence we said to him "Stalagmite". (Which indicates all are in consensus that he is done talking and should stop before he looks even more dumb)
