loud mouthed bitch
large mouthed bitch
large mouthed bass
all of these terms are used to describe a horrible, loud and obnoxious/disgusting woman that takes a lot of dick in and around her mouth or any other hole that she can find on her own body. LMB's are known to ruin lives, sucker men into nailing them, getting STD's, and causing extreme mental suffering to an individual or a group.
