"ALSer" means a person with amyotrophic lateral sclerosis (als). It is one of many casual words teens pick up from friends, social media, music or sport, and on its own it carries no particular warning. If you hear your teen use it, it is fair to ask what they mean by it in their friend group, since meanings drift quickly.

For ESL learners
"ALSer" is informal English meaning a person with amyotrophic lateral sclerosis (als). It is used widely across English varieties. A more formal or neutral equivalent would be something like "a person with amyotrophic lateral sclerosis (als)" expressed in standard vocabulary. A common mistake is to assume "ALSer" can replace its standard equivalent in every register; keep it for spoken or casual situations and use the formal form in writing. If you are a B2 or C1 learner, it is useful to recognise this word when you hear or read it, but think carefully about whether the situation really calls for it before using it yourself.

(Internet slang) A participant in the Usenet newsgroup alt.life.sucks.
Good point. A blanket apology would be a good place to start if he really wants to be an ALSer. It will take a year or two to post the HUGE number of apologies he owes ALSers.

For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
