to be the last person somebody text that day. The most intimate text goodnight is when that person is actually lying in bed or at least says they are lying in bed. "Text goodnight"s are generally not sexual and because of that sometimes more intimate.
Lynzie and I texted until 3 in the morning, then we text goodnight.
Billy: He's a douchbag.
Lynzie: Yup. Well, I gotta wake up in like 4hrs.
