Someone who's clueless or dim-witted, basically a total blockhead
"Grabe ka naman, ang torpe mo talaga!"
Wow, you're seriously so stupid!
super shy around the opposite sex, like totally awkward and tongue-tied when trying to flirt or talk to someone you're crushing on
"Ang torpe ko talaga, hindi ko masabi sa crush ko kung gusto ko siya."
I'm such a shy guy, I can't even tell my crush that I like her.
