What's an equivalent replacement for the word "lame"?

I don't know if I'm just becoming overly sensitive to my own language or if this is an actual issue, so feel free to let me know if it seems that I just need to grow thicker skin, but still.

I keep getting this uneasy feeling whenever I use the word "lame" and I think it's because I'm starting to realize it's technically ableist. However, there's no single non-profane word that I know of that fits the niche that I use it in.

For example, I wrote out something earlier about a behavior I do that I don't like that I do because I think it's kind of shitty behavior, but it's overall harmless. I use lame to describe it casually. I could also call it kind of shitty, as I did before, but not to audiences that I don't want to use profanity around.

Anyone know of a word I can replace "lame" with?

I'd say maybe weak, but that's got its own baggage that I'm not sure I'm ok with switching to. Annoying is too strong of a word for what I'm going for. Maybe lame is a short word for "this makes me feel slightly sad"?

Idk, so I open it up to the public: Is this even an issue or am I being too sensitive? Could this be solved in a single replacement word or do I need a whole ass phrase to express this?
