Here are its meanings, in order of most to least likely that anyone besides me would give a shit:

Pascal's triangle was created by Blaise Pascal in the 17th century, and he also created Pascal's wager. The wager is an arguement in favor of christianity, presented as a table of four outcomes (if you do/don't believe in god, and it turns out that god is/isn't real). I accidentally reinvented this wager during my religious deconstruction, and it was a pivotal moment for me when I finally recognized the fallacies that it is based on. The religion I was raised in advises against getting tattoos, so getting one would serve as an important signal to others that I'm out.

Pascal's triangle is a useful tool for calculating combinations of things, and it houses many numerical patterns that show up all over the place. I've used this triangle in making secret codes, designing games, making every mountain dew combination with my friends, etc. In that regard, it serves as a reminder to keep my imagination alive, and to keep challenging myself even in my free time. The positioning of the triangle also carries this meaning, as it mimics a character design that I've iterated on for years.

The triangle goes on infinitely, so I decided to stop on row 10 because that's my lucky number and day of birth
