WYLL is an acronym often used in casual conversations asking someone what they are up to or how they are feeling. For example, if you text a friend, "Hey, WYLL tonight?" you are inviting them to share their plans with you. It is a personal way to check in and show interest in someone's life. Most of the time, people use WYLL in text messages, social media messaging, meetings, or just chats with contacts. The very informal nature is hardly suitable for any other setting and gives the impression of casualness. In all, it supports light and entertaining conversation.
