After that dude got his ass beat at the party, he totally thesis'ed out.
So this chick was all over peter the other night and she asked him back to her place, he declined and went home and played gamecube instead, man only fag would thesis out like that.
After the thesis is created you must supply an argument to defend your work when it is shown to other people (i.e. teachers, pupils, etc.).
That's... err... some pretty interesting theses you got there.
