I love you with tuberculosis
TB is like being in love but also having a disease. 'I love you with tuberculosis' means I love you but also I’m going to cough on you and make you sick. It’s for people who are too lazy to end a relationship but still want to complain about it.
My sister said that to my brother when he forgot her birthday.
My mom said that to my dad after he ate her favorite cake.
My friend said that to me after I spilled soda on his shirt.
