A Manly yet, cute boy. often girls fantasize over a Trentin. If the Trentin is disrespected by anyone he will snap and make the person's life very unenjoyable. the trentin is sort of tall with great hair, has a laugh and smile that would make girls take their clothes off in an instant. The sex organ on a trentin is also very impressive.
guy - "holy shit! how does trentin pull bitches so hard?!"
girl "OMG, TRENTIN IS SOOOOO HOT"
Guy - "remember that one time trentin came to that party, and 50 girls ran up to the top floor bedroom with him?"
The action of giving a gift known to be damaged in some way rendering it useless to the recipient. Arguably a representation of "It's the thought that counts" to its very limits.
Dude, are you seriously trenting that broken cup as a Christmas present?
