Waitrose : glad you enjoyed my sideboobing !
I myself have personally never sideboobed. I presume to do so would involve not wearing a bra. If I did this I would be waist boobing, not a look that anybody wants to rock or tote.
Just thinking how you would decline the verb:
I sideboob
You sideboob
She sideboobs
They Sideboobed
Beat that Tom with your double first in Classics (just bitter cause I only got a 2:2)
