Sans doesn't call Frisk "old lady".

SPOILERS so don't read the rest if you don't want the game spoiled:

Sans is refering to TORIEL, who, as stated by him, made him promise that he would never hurt a human.

' "If a human ever comes through this door... ... could you please, please promise something? Watch over them, and protect them, will you not?" Now, I hate making promises. and this woman, I don't even know her name. But... someone who sincerely likes bad jokes... has an integrity you can't say "no" to.'

When fighting Sans, he says "Welp. Sorry, old lady. This is why I never make promises." (talking about Toriel)

Also, in the genocide route, when first meeting Sans, he says, "(gee, lady, you really know how to pick 'em, huh...?)"

This is also refering to Toriel in regards to her picking odd humans to save. He expected an average human. Not a genocidal maniac.

Hope this helped :)
