Tim doesn't have the guts to take on ed, due to fear that he will look like a dick head in front of his fellow housemates.
Tim accused Ed of being gutless because Ed wouldn't stand up to tim(he said it to Drew behind eds back the other night), yet Tim doesn't have the guts to say things to Ed. Instead he goes to Drew, and now Justynn after tonights episode to bitch about Ed, and discuss ways to bring him down.
Gutless is defined as lacking courage... Tim doesn't have the courage to take on Ed one on one, instead he continues to opt in the way of manipulation.
And that is why A) He won't win and B) He doesn't deserve to win.
Honestly, i can see how Ed is also being 'Gutless', but i just find it rich on this board how everyone hates Ed because of it, yet tim does the exact same things.
