Here you go

Go to....

Admin CP -> Styles & Templates -> Style Manager -> ? ? -> Threadbit Templates -> threadbit

Find the code below and just add the red bit

$thread[movedprefix]
			$thread[typeprefix]
			<a href="showthread.php?$session[sessionurl]t=$thread[threadid]$thread[highlight]"><if condition="$show['gotonewpost'] OR $show['sticky']"><strong>$thread[threadtitle]</strong><else />$thread[threadtitle]</if></a>

The strong tags above is what makes the title bold

or another way...

Admin CP > Styles & Templates > Replacement Variable Manager > Add New Replacement Variable

In the Search for Text field, I typed 'sticky:' and in the Replace with Text field I typed <b>.

That removes the word Sticky: from those threads but the entire title is bold.

Hope it helps
