 Get the if looks could killmug.
Get the if looks could killmug. A phrase used to denote a glare or angry look at someone that is so intense, it would kill someone with just the intensity of the emotion behind it (if that were possible). Typically used when someone is extremely angry about something but can’t openly speak about it.
