calves and ankles with greater circumference than normal, bearing similarity to baby elephant legs and young trees, hence jumbo + stems. Often covered by brown woollen socks to inadvertently accentuate mass of lower leg. See also cankles, but note jumbo stems have different ratio to knees and thighs. Sometimes refered to as Christian legs
From the silhouette I thought it was Jaja Binks, but then realized it was Greta with her jumbo stems.

a stem cell is a cell whose function has not been decided. stem cells have the potential to become any type of cell that exists, at least in humans. every person has stem cells, but the older you are, the harder it is to find these cells, because less of them exist. the most easy place to get these cells from is the BLASTOCYST form of fetal development; herein lies the bige controversy of embryonic stem cell research
an example is someone who has diabetes. this disease causes cell in the pancreas to stop functioning and eventually die. stem cells have the potential to repair the problem before it even happens.

When using a glass pipe there is always that one tweaker who is waiting for the pipe to be set down so that they can burn your stem down for another hit after you leave the room. Wrapping the stem of your pipe with electric tape can be an effective counter.
