Someone, mainly females who stick around in an emotionally abusive relationship with a compulsive cheater. Due to the cheater keeping and treating their mate as their pet the mouse stays regardless because it's the only love she receives. Even though deep down they know that love for them is superficial or even fake they convince theirselves that it's real. They deal with the partners cheating manipulative ways just like a good loyal little pet.
Who cares, your girlfriend is a mouse. Therefore you can literally do whatever you want knowing she will never leave you. You can probably bang another girl in the next room and she wil turn away and possibly cry but she won't do nothing about it cuz she's a mouse, you got her pinned down so she ain't going nowhere

Get the Fancy Mousemug. Mackey Mouse is a pet owned by La Salle College. She deliberately used the linguistic bible in order to get 500 hundred million pounds. She always shows perseverance on the linguist device, stylistic device and structural device deliberately. If you did not use them, she would say NONONO and try to persuade you to read more books on the way to school and on the way home to deepen your intellectual depth. Never bring your English materials back home or else she will shout at you in Kowloon City.

Get the Mackey Mousemug. When you are receiving a blowjob and just before the big moment you remove your member and with a sideways hip thrust you toss your balls over the side of your dick making it look like "Micky Mouse" and as a her head turns to the side in confusion you finish but only echoing the words "OH BOY" in a mickey mouse's voice. Please note - this should only be attempted after age 45 due to ball elasticity logistics unless you have had your balls "lowered".

Get the Naughty Mousemug. Slightly tugging on a woman's tampon string giving her an excited fright. This should be done without her knowing what is happening.
Stu slides his hand up Stacey's leg and quickly tugs her tampon string hanging out her vagina.
Stu: "yo, i totally gave Stacey a Mouse Tug last night"
Dane: "mean! High Five!"
