I looked in my precious Oxford Concise English Dictionary, Ninth Edition, and I found out why women would only be happy with a real man:
mouse // n. & v.
n. (pl. mice //)
1 a any of various small rodents esp. of the family Muridae, usu. having a pointed snout and relatively large ears and eyes. b any of several similar small mammals, such as a shrew or vole.
2 a timid or feeble person.
3 (pl. also mouses) Computing a small hand-held device which controls the cursor on a VDU screen.
4 slang a black eye.
v.intr. /also /
1 (esp. of a cat, owl, etc.) hunt for or catch mice.
2 (foll. by about) search industriously; prowl about as if searching.
mouselike adj. & adv.
[Old English mus, pl. mys, from Germanic]
Definition number 2 is under the spotlight.
This dictionary defines timid and feeble as follows:
easily frightened; apprehensive, shy.
1 weak, infirm.
2 lacking energy, force, or effectiveness.
3 dim, indistinct.
4 deficient in character or intelligence.
6. mentally deficient.
from Latin flebilis lamentable, from flere weep]
pretty decisive ..... ;-)
