Loach

Noun describing a friend or relative who stays at your house or event longer than they are welcome. Typically it is used to describe someone who is closer than an informal friend. Family and friends who you feel an obligation to are the most likely candidates to illustrate Loach-like qualities.

There is no time limit to overstaying their welcome. For instance, a family member who stays for one day after Thanksgiving might not be a Loach, whereas someone who stays for 30 minutes after the last guest has left, might be a Loach.

“Steve is such a Loach, he stayed at the party a full hour after everyone left.”

“We better have a plan for your Aunt when she comes to dinner. She’s can be a Loach and want to chat forever.”
