White's triangle tattoo on his chest was on display a few times during the 11-season runtime of "Shameless." While some people thought the ink was added to Lip's character and speculated on its meaning, the tattoo is actually part of White's personal collection.
When asked what it means in an interview with Fox, White said, "I appreciate your question, but it's a really lame answer I have for this. The triangle tattoo was for a couple of friends. I got it when I was really young. I was like 17, and it was done very poorly, so it's very raised."
He explained that the show initially tried to cover it up, but because it's raised, the makeup artists had trouble disguising it. "We ended up asking the tattoo artist if I could have his tattoo on my body, so Lip ended up with the tattoo as well as myself," he said.
