A man broke into his next door neighbour's home and trashed the house when a long standing dispute erupted, Lincoln Crown Court was told.
Daniel Davy banged on the front door of his neighbour Tracy Wood at 2 am and then began smashing the windows.
Tony Stanford, prosecuting, said that Ms Wood and her son fled from their home in Garfield Close, Ermine West, Lincoln, and sought sanctuary in a neighbouring property while police were called.
Officers arrived to find the house had been smashed up. Davy , who was armed with a cosh, was detained after being warned he faced being tasered.
He told officers "I'm a Sheffield boy not like these Lincoln pussies.
"When I get out of prison for this I'm going round there with a shotgun to finish them off."
Mr Stanford said nearly £7,000 worth of damage was caused to the property.
"The double glazed windows in the lounge were smashed. The upstairs bedroom windows were cracked.
"The Sky dish was damaged. There was blood on the television and hot drink thrown over the walls. The fridge freezer was overturned.
"There was blood all over the kitchen. The kettle was smashed. A DVD player and the television digi box were smashed.
"In the son's room the television had been smashed. The toilet seat in the bathroom had been ripped off and thrown downstairs. Paint had been thrown against a door and there was blood on the carpet.
"There have been ongoing problems between the two families. Both parties have called the police on occasions to complain about the other."
Davy,32, of Garfield Close, Lincoln, admitted burglary on 17 August this year. He was jailed for 32 months.
Recorder Mark Rhind told him "You terrorised your neighbours and completely trashed their house going from room to room.
"You are a grown man. You are at the point where you should know far better than this."
David Eager, defending, said Davy reacted because he believed his girlfriend and child had been threatened.
"He is quite properly thoroughly ashamed. He completely lost the plot. He plainly has anger problems.
"It is clear there has been fault on both sides but none of the actions of the neighbours could justify the entire over-reaction by the defendant."
