An asterisk ---> ( * ), is a symbol found on the keyboard that is used to call attention to a reference, the symbol also appears in many advertisements, and this symbol is widely used in the Roleplaying genre of Roblox, basically, the Asterisk symbol starts at the beginning of a roleplay sentence and also is added at the end of that sentence.
Margetta states that: she loves the Among us meme. (Then add an asterisk)

(but if you used it in the Roblox roleplay genre)

Damon: Man, do you really like small ones?
Rob: Yes.
Damon: Oh great, i know this girl and i'll introd---
Rob: Because the big ones break my asterisk.
Damon: Oh for f*cks sake Rob.

Fame or achievement tarnished by either facts (steriods in Barry Bond's case) or sour grapes.
Barry Bond's record is asterisked thanks to his romance with Balco performance-enhancing products.

Don Shula wants the Pat's 19-0 season asterisked becuz they filmed the NY Jets defensive signals at the start of the 2007 season. Like no team has ever done something like that before, lol.
