Ser
Ser is a playful misspelling of sir used on crypto social media to address other users, often with mock politeness, affection or plain irony.
The spelling imitates a common way the word sir is written in some online communities and was adopted by crypto Twitter as an in-joke around 2021. It appears in replies such as gm ser, wen token ser or this is financial advice ser, and is used for anyone regardless of gender. Its tone ranges from friendly to sarcastic, often as a gentle way of pointing out that someone has missed something obvious.
Like gm, wagmi and probably nothing, ser works as an identity marker: using it shows familiarity with the culture. Projects and brands adopt it to sound native to the community, with mixed success.
The word carries no meaning beyond tone, so it is irrelevant to evaluating any project. Because some critics consider its origin mocking toward particular groups of internet users, it can come across as condescending outside crypto circles, and its use in professional communication is generally avoided.
Example
A user asks in a project's chat when the token will launch. Another replies: ser, the date has been pinned in the announcements channel for a week.
