This is The Blob Family.
(If you don’t get it, ask your designer friend)
I don’t get it :( Someone please explain?
It’s a design reference and saying the Blob Family is like a font family made up from different font weights. The numbers normally represent a font’s weight like 55 is Regular, 56 is Italic, 75 is Bold etc. so Regular Blob, an Italic Blob, a Bold Blob and all those together make a Blob Family.
I giggled when I saw it :D
