''Butt 'Plugs''' are a popular type of hard-bodied [[fishing lure]]. They are widely known by a number of other names depending on the country and region. Such names include '''crankbait''', '''wobbler''', '''minnow''', '''shallow-diver''' and '''deep-diver'''. The term '''minnow''' is usually used for long, slender, lures that imitate baitfish, while the term '''plug''' is usually used for shorter, deeper-bodied lures which imitate deeper-bodied fish, frogs and other prey. '''Shallow-diver''' and '''deep-diver''' refer to the diving capabilities of the lure, which depends on the size of the lip and lure buoyancy.
